SPANNERS,BANNERS
and FLAGS
To Top
This next incident I have briefly
included as I now find I quite amusing, although at the time it
could have been a rather nasty. We had been experimenting with
banner towing on our paramotors for a while now, as this was a
cheaper alternative for clients than branding separate wings.
The problem that kept arising was that one side of the flag kept
folding in whilst in tow. To alleviate this minor set back we
figured a weight hanging off the rear corner was in order. As
we were now in the field, the only heavy object that was available
was a number 34 spanner. For those of you not aware of spanner
sizes, this is a rather large and solid chunk of hardened steel.
This was duly attached to the lower end of the flag and towing
attempted again. Take off was accomplished by the flag either
being rolled up and placed in a pocket and once airborne, dropped
below, else it was laid out behind where it automatically inflated
as the glider was pulled up. (Banners may also be attached to
the trailing (rear) edge of the glider). Once in the air I dropped
the flag and looking back was delighted to see that it was flying
almost symmetrically. Figuring that it was now time to show off
our new prototype, I entered a tight powered turn, which throws
the wing due to the centripetal force into a quite spectacular
bank with the pilot sitting almost on the same horizontal plane
as the top of the wing. As one initiates the turn a fair amount
of height is lost until the wing starts to regain the required
airspeed once more. Completing the 360 turn, I was amazed that
almost everyone close to me was prostrate on the sand, with my
mate wildly gesticulating and holding his head in what seemed
to be utter panic.

Those spectators further away seemed
to be in various stages of unrest and far from the serene and
tranquil images one associates with family outings to the beach.
I had forgotten that the spanner was now hanging another metre
below the bottom of the engine set up, which now resulted in it
entering a suicidal ark as it was spun outwards with each turn
in a death defying vengeance. It had come within inches of decapitating
a beach walker who was still mindlessly ambling along, ignorant
of how close he had come to death, and wondering what on earth
everyone was doing face down on mother earth. After this little
episode we placed the spanner into retirement and opted for a
diving weight instead. As you will see in the next article during
the early research and development stages, that guardian angel
certainly had its work cut out again

ARRESTED
To Top
While in the vicinity of the African
Equator, here is a story that materialised along similar latitudes,
however closer to the madness associated with this continent.
My self and a fellow pilot were attempting to fly our powered
paragliders from the base of Kilimanjaro (the highest mountain
in Africa), back down south into South Africa (a few thousand
kilometres). Our back up vehicle was a sponsored fiat uno, and
of those of you that are aware of the logistics in Africa, you
will be aware that some pot holes are way bigger than our tiny
vehicle and trailer! Arriving in what we were later told was the
small Serengeti national park, we found the only open piece of
flat ground, and started to lie out our gear. A slight problem
soon materialised in that this vlei happened to be ankle deep
in water, however we managed to drape the wings over the taller
ground cover extending out from the marsh. This was going to be
one hell of a take off, with no wind, running in marsh water with
lots of tall trees around us and a herd of nervous looking buffalo
slightly behind us. (There are many parts in Africa that host
wild life, however are not classified as official national parks.
Rules and regulations appear and disappear on this continent when
and how it suits the relevant authorities best). We figured that
if however this was a national park, there should have been some
indication and if push came to shove we would tell them we had
made an emergence landing (which you are allowed to do in aviation
circles, and were simply taking off again). Africa is renown for
its capitalisation on anything that has the potential to extort
money, goods or anything else lacking at that precise moment.
This activity was in the middle of the bush, with very little
signs of civilisation around, however out of nowhere arrived the
parks department, which soon was followed up by the police and
later the military.

Typical questions followed suite,
such as'' "what are you doing?'- We taking off. "You
not allowed to"- why not, we had engine problems. "This
is a park, these machines are not allowed"-well where does
it say that, do you even know what they are? This continued for
a while until I informed him we had clearance to fly through Tanzania's
air space (which we did), 'But not in here he answered".
This discussion was stagnating with neither side backing down,
hence we were marched off to a bush camp and placed under armed
guard while more senior personal were being summoned to deal with
the situation. Our back up driver happened to be a fat lazy ex
South African military colonel of some type, who was told to wait
by the car while we were being detained. After about four hours
of waiting I had had enough, and informed my partner that I was
leaving, simply walking out of this camp back to the car and getting
the hell out of Tanzania as fast as possible. He was welcome to
come along. This reopened frantic radio correspondence with head
quarters with us being informed that back up was only minutes
away. We were marched back to the road, again under armed guard
where a posse of high profile looking vehicles was waiting for
us. These were the big knobs, and who were looking most disgruntled
for being awoken at this unearthly hour of the night.
Using the expected form of initial
intimidation we were told they were going to lock us up until
a court hearing a few days later. Knowing that everything in Africa
is negotiable, leaving in most instances an escape route, and,
as with part of any psychological 'warfare' which involves not
immediately showing fear or weakness to proposed threats, yet
maintaining courtesy, I seconded this motion that we be locked
up as we hadn't done anything wrong, of which our driver nearly
had a coronary. "That's fine I said, tomorrow we phone our
embassy and they will secure our release, you could be in trouble!"
This placed them now in a position of bureaucratic indecisiveness
(although not showing it). Ideally it was in their own interest
to settle this now, walk away with the usual bribe, or run the
risk of not receiving anything and possibly release us free. If
they had opted for the latter this could in these circumstance
be re negotiated and therefore plan B certainly existed. A few
hours later, now well after midnight we arrived at an acceptable
fee, whereupon we were given an honouree escort back to the main
road, and hence began "The African powered paragliding expedition".
A shortened version is posted on my web site under 'various adventures'.

DIVING IN ZANZIBAR
To Top
One of my closest encounters with
death, and one of the very few times I felt my self on my way
out was during a deep dive off the northern tip of this island.
When diving with compressed air as in scuba, you have a set of
tables to follow. These tables document the amount of time one
may stay underwater, without toxicity from the oxygen in the compressed
air and the narcotic effects of nitrogen as one descends. (This
narcotic effect from nitrogen has been responsible for some quite
bizzar behaviour from divers. Some just sit and laugh, some contemplate
life while others have been known to offer their regulator and
air to various creatures!) Secondly tables allow the diver to
safely come back to the surface without any adverse effects from
the nitrogen bubbles that have collected in your tissues, and
which now are expanding as you ascend (due to the drop in pressure
as one rises), and working their way out of the body. The longer
the diver stays under water and the deeper he or she descends,
the more toxic the oxygen in the air becomes, which eventually
will result in seizures, paralysis and death. Secondly the deeper
one dives on normal compressed air (in comparison to mixed gas,
where the quantities of oxygen and nitrogen are minimized and
often replaced with mixed gasses such as helium), the more the
narcotic effects that nitrogen exhibits, are experienced. Thirdly
the more nitrogen is absorbed (from diving deep), and which being
an inert (plays no part in body metabolism) gas, must therefore
'bubble' out of the divers body on the ascent. Too many bubbles
and too big a bubble from a fast ascent will result in an embolism
where it lodges in the joint, brain, heart or other vital organ,
and again death or if you lucky extreme pain (the bends). Now
that you have had a brief lecture on the physiology of diving
let me explain to you what happened.

With my job dictating I was diving
every day, and up to three times a day, ones body becomes accustomed
to the adverse effects of both nitrogen and oxygen, with us regularly
diving to 50-65 metres in depth. Conventional diving tables usually
list a safe maximum limit of 30- 40 metres as the safe lower limit,
and like most listings, I believe there certainly is a big safety
margin built into it. On this eventful day a fellow diver and
myself had planned a dive to around 70 metres, and with a spare
cylinder tucked under our arms, down we went. Familiarity certainly
breeds content as we continued down wards and not really checking
our descent rate. Hitting the 75-metre mark was where the effects
of nitrogen quickly became apparent. Suddenly and within a split
second I felt myself passing out. For those of you that have ever
been under anaesthetic, it was the same feeling as being put to
sleep. A really great feeling but at the most inappropriate time
and place. All I knew that if something was not done quickly,
I would be unconscious and drown within seconds. I remember hitting
the inflate button on my buoyancy jacket to try and arrest my
descent and take me back up where the effects of nitrogen would
be lessened by the reduction of water pressure. This in it's self
is potentially life threatening, due to the air inside the jacket
now expanding, resulting in a 'run away ascent' and nitrogen bubbles
expanding beyond the safe limit and or lung damage from air volume
increasing inside the lungs. I must have briefly passed out and
gained consciousness a few seconds later at around 65 metres,
which was sufficient to minimise the adverse effects of nitrogen
narcosis (commonly called 'rapture of the deep'). Luckily I had
been diving with a dive computer, which was now flashing SOS,
however still giving me a recommended ascent rate and decompression
stops, to allow excess nitrogen to leave the body before continuing
upwards. On reaching the surface I immediately lay still for a
few hours in order to limit metabolic activity (another contributing
factor to 'the bends'), while drinking copious quantities of water.
The nearest decompression chamber was on the mainland at the port
of Mombassa in Kenya, a good days travel away. One simply lay
there while the excess nitrogen worked it's way out of the body,
while at the same time expecting those tell tale signs of 'the
bends' to surface. (I have experienced this ailment, and on one
occasion so severe that simply breathing was near impossible.
The bubble had obviously lodged in part of the lung or muscles
associated with respiration, and thus caused excruciating pain
with each breath. This stemmed from a search and recovery course
I was running where one of the students overfilled the lift bag,
forgot to vent the air as it rose and hung on to the ascending
bag. To prevent a catastrophe of unprecedented proportions, I
hung onto the student while attempting to free her from the bag.
We were dragged upwards for a distance before freeing the bag,
and obviously this sudden reduction in pressure was enough to
over expand a few bubbles). Both of us were bent for quite a number
of days).

Back on the dive boat, a local dhow
converted for dive operation, we were making progress back to
shore when the engines decided suddenly to pack up (a common occurrence
in Africa), hence the reasons we carried sails. These were hoisted
and our journey resumed again, only to be interrupted once again
by the sail tearing lose from the rigging. So here we were in
the middle of the ocean with no means of continuation, and a boatload
of clients. I thought to my self at this stage, what would have
happened if either one of us had experienced the bends. If we
had and it was life threatening we surely would have expired.
As we had a radio and were able to eventually summon help, we
eventually vacated the last client from the boat at around 1am,
in pitch darkness and pouring rain while being ferried to shore
in what resembled a tin toy dinghy. We the crew swam the few kilometres
to shore the next morning as I had a plain to catch later in the
day back to South Africa.
During my days off I used to go
and dive with a group of "poachers", if they could be
called that. In Africa the term "illegal" is a subjective
word. Is something illegal because the rest of the world deems
a certain activity out of bounds, yet may be practiced and sanctioned
under the auspices of the present government. Who decides weather
a certain activity should be banned or not? Try telling a starving
man he can't collect a certain commodity when his family is hungry
because of a worldwide scarcity. The problem arises in that any
activity may be condoned with enough money in Africa. Sea cumber
diving has developed into a lucrative multi million dollar trade
up the entire east coast of Africa. These sea creatures resemble
sea slugs and can be found lying about the ocean floor at various
depths. When disturbed they ooze their intestines out in a sticky
liquid. Many an unsuspecting student has been caught by shaking
the creature and quickly before it has time to expel it's contents,
hand it to an apprentice, which in no time has a slime stickier
than super glue over his or her appendage. These sea cucumbers
are dried and then exported to the East for a variety of medicinal
and other purposes. Diving with these poachers defies all diving
laws and certainly shows that an incredible immunity to various
under water ailments may be attained. Either this was possible
or they quietly went off and died without anyone being aware of
the causes. Although many of them were bent on numerous dives,
they continued their plunder of the deep. They used no buoyancy
vests, used rocks as weight belts, some had no depth or pressure
gauges, they used no snorkels and some had no fins. They had absolutely
no idea of any diving related injuries. They desecrated corel's,
shells and fish alike. Anything that was in killing distance was
taken. The diving depth made no difference to any of them and
for many the dive time terminated only when their air ran out.

Because of the scarcity of these
ocean slugs we would have to travel out to sea for up to three
hours in one of their home built wooden boats. Each of the divers
had up to five full diving cylinders and would exhaust each one,
have a smoke break between changing over and commence diving again.
At the end of my second dive with them, my dive computer was showing
danger levels of nitrogen saturation for the time and depth we
had been diving at and was recommending no more diving for the
next two hours. They were planning another three deep dives with
only about five to ten minutes between each. I took the liberty
of attaching my computer to the arm of one of them for these remaining
dives. The resultant recommendations it gave for safe continued
existence was astronomical, and certainly no where within their
realms of diving practices. This really was an experience that
would go down in my diving archives.
Fishing with dynamite is another
common occurrence along the African coastline and areas up near
Asia. On numerous occasions I would be under water with a group
of students when an almighty blast could be felt under water.
Cautiously surfacing one would find ones self surrounded by fishing
boats, nets and dead and stunned fish amidst the smell of cordite.
On more than one instance an anchor has been dropped from a local
fishing boat unaware of my diving buoy on the surface, narrowly
missing me on the bottom and smashing into pristine coral formations.
This unfortunately is life and the reality of Africa.

EXTREME
EXHAUST
To Top
One of my first advertising contracts
was for the well-known cigarette group Gunston. This brand had
sponsored the world-renowned surfing event
 
"The Gunston 500", which
became a household name in Durban South Africa for 30 years when
suddenly they were informed due to the ban on smoking advertising
that they were no longer welcome. Rather preposterous when you
take into account the annual revenue generated by this event and
the numerous other vices in life, which are probably far worse,
that a bit of cigarette smoke. We had come up with a rather unique
method of promoting various companies. The idea was to strap an
engine and propeller on ones back and attach this to a large parachute
with the clients name on and fly over stadiums and various events
(for a fee of course) as a form of advertising.
My job was to fly just off the shoulders
of a number of jet skis as we proceeded in from behind the breakers
out at sea. (In those days there was no such thought regarding
safety margins such as gliding distances back to shore should
the engine die while out at sea). Being stressed already from
having engine problems with our home made paramotor on the first
day of the beach festival, I had forgotten to check that my exhaust
was secured, and out to sea I flew. I had no quick releases on
my harness, and had instruments that were secured to my leg and
harness at the same time, effectively locking me to the set up.
On reaching the beach I noticed I was receiving more than my usual
amount of attention, with virtually every flat window hosting
what I thought was a friendly waving tenant. So I flew closer
and waved back. What had transpired was that half way back to
shore my exhaust had fallen off and disintegrated half my prop.
How it kept running I have no idea. The engine was a high revving
design, which combined with a few holes in the exhaust, had resulted
in my being accustomed to loud flights and thus I had not realised
three quarters of the actual pipe was absent. The spectators on
the beach and in the flats were obviously waving abuse at me due
to the excessive noise factor, which I reciprocated with a friendly
wave back. (Take the exhaust off a high revving go-cart, place
it by your ear, rev it full for an extended period of time and
understand how traumatic it can become).

Looking back, my concern here is
how close I really came to dying. If the exhaust had damaged slightly
more of my prop to inhibit enough thrust to sustain flight, I
would have hit the waves and sunk. There would have been no way
to exit my harness and accessories, and I would have hung four
or five meters under my inflated canopy on the surface. Looking
at the positive side, my sponsors could not have asked for better
publicity. Having their name and logo on my canopy, forced everybody
to view this branding as they waved, shouted abuse and performed
every other antic against this vile form of noise contamination.

THE DAY I
DETATCHED MY FOOT
To Top

The day that I detached my foot
from my leg began with a new paraglider I was test flying. In
retrospect this should have been done over water or sand, however
this particular wing had been tested without the motorized counter
part, with good results, so I figured it was more than likely
ok. The minute however power is added, a pendulum action is set
up, which has the potential ability to compound any small variances
not experienced with non-powered flight. Over and above this I
was flying a propeller set up I had just built for a friend, who
happened to be present for it's maiden flight. On top of the hill
were also a number of students, neighbours and fellow pilots.
I clipped in, pulled up the wing, turned around and within a few
steps was airborne. Everything felt good while I turned back towards
take off in a fairly sharp one hundred and eighty degree turn,
and then suddenly there was that unearthly feeling of the wing
beginning to slide into a negative spin. What happens is that
if a number of lines, especially the rear ones are shorter than
usual, the glider is actually flying just off the stall speed
(the attitude and speed of the wing where it will stop flying).
When this angle is increased by one of many factors, such as adding
power, either or both the wings will stop flying. If one side
stops the other wing will fly around this stationary side, with
the stopped side falling backwards in what is termed a negative
spin. Various wings will react with varying degrees of violence
to this manoeuvre, however the common factor is a great and rapid
height loss. I happened to catch it before it entered a full spin,
however this transition put the wing now into a 'parachutal stall'.
The canopy is open and inflated however there is no aerodynamic
airflow over the wing and the only direction one is flying is
vertically down wards. (In this case faster than normal due to
the extra weight of engine, propeller etc on my back). There was
simply no time to rectify anything as I was about to hit the ground
amongst a rockery of objects and what's worse, with the wind,
making the impact velocity around fifty kph. The only thing left
to try was apply full power (which in reality is not the method
used to exit such a situation, however no other option was left)
and try and 'drag' the wing away from the mountaintop, gain height
and rectify the situation. This did not materialise and I remember
thinking 'dam it, now I am going to have to fix this retched propeller
again'. I remember seeing the ground coming up rather quickly
and the next minute heard the prop break and suddenly I was back
on the ground. Looking down I found it rather strange to be looking
at the sole of my foot, with the actual foot a good 100mm`s away
from where it should have been on the end of my leg. Very strange
I thought, something certainly looks a bit cockeyed. Both tibia
and fibula had broken with the tibia also dislocating from the
joint inside the foot and violently ripping a hole through the
side of my ankle where it exited.
X rays showing the breaks and dislocations- the
circles are areas that normally should be joined together
This exposed bone was now firmly implanted in
the earth, which had occurred as I attempted to stand up. My efforts
to secure a camera to document this hopefully once in a life time
experience were thwarted by bouts of nausea, vomiting and chain
smoking spectators and my main regret today is that I never managed
to document this occurrence. Failing to secure a helicopter to
transport me to hospital, I was driven in the back of my van,
while a mate was holding my detached foot to my leg, which was
attempting to disjoint it's self with every bump we encountered.
More painful was the fact that the entire bone was sticking out
and now had the wind from the open back van blowing against it
and although only half an hour to hospital, believe me it seemed
like eternity. Arriving there required a further wait while they
now splinted my foot (which required them to move it again) and
x-rayed it. The pethadine that they gave me certainly did not
seem to make any difference and my answer of 'gravity' to their
question of 'any allergies' were met with stares of unearthly
proportions.

A few weeks after skin graft, with surface bone visible. Area
on upper leg where skin was "borrowed from"
Back on the hill, before anything else was decided,
the proposal that a pub and alcohol was in dire need resulted
in a procession into town to acquire copious quantities of this
substance. Those left guarding the equipment simply had to wait
while normality was restored and sanity regained. Well to cut
a long story short, the puzzle was put back together, however
the wound was left open for a week while I was fed massive doses
of antibiotics to arrest the infection in the bone and surrounding
tissue. Every second day I was back into theatre to remove the
dressing and clean the wound, and seven days later a large piece
of skin was taken off my upper leg and grafted over the wound
to try and close it up. Miraculously the infection, which was
now present around the pins in the bone, disappeared and the skin
graft even took directly on the anklebone, which apparently in
most graft case is fairly unusual. During these two weeks in hospital
my mother, nearing eighty, would make this arduous trek religiously
every day on here false leg, which is an incredible feat. I think
my Dad unbeknown to all of us, was starting to suffer from heart
failure, so to the best of his ability, he admirably attempted
visits when he was up to it. Another person who religiously was
at my bed side every day was a remarkable girlfriend, Avril Hattingh,
who I would say managed and offered care far exceeding that rendered
by the hospital staff (and bear in mind this was a private, upmarket
hospital). Nearly three years later it still does not bend and
is extremely painful to weight bear on, however I had my first
flight four months after the accident, which required me to take
of and land on the good leg and a helper or two to help collapse
the wing, thereby preventing me from being dragged by the falling
wing forwards. Sometimes I think it may be better for logistical
and practical reasons to have it chopped off, a prosthetic leg
attached, which will normalise my activities again and (a lamp
holder made out of my lower leg, with the on off switch being
one of my toes), but up until now, and I don't know for how much
longer, its still on the end of my appendage.
