- I've had all sorts of crashes while learning how to fly, and after I learnt
- how to as well! One of my luckiest crashes was just after I felt confident to
- fly solo, it was a windy day and a couple of us had launched to quite a good
- height (a bungee (histart ?) is really good in high winds) and I was geting an
- amazingingly long flight, the only problem was that my glider is designed for
- thermal soaring for beginners, and without heaps of weight added into it it has
- very little penetration in high winds. This soon became apparent when I
- stopped playing around and tried to come back after floating a LONG way down
- wind, I had plenty of height but just could not come foward eventually I gave
- up and just concentrated on landing it, which became increasingly diffcult as
- it got lower and finally dissapeared behind a hill in the distance, nothing you
- can do here except pull full up and hope for the best. Eventually I finished
- packing up and off we went to look for it, we found the glider nose down,
- buried all the way up to the wings in mud amongst mangrove trees, I was lucky
- that the tide was out at the time. The only damage done was one muddy plane
- and radio gear that needed drying out.
-
- A really neat looking crash that happened one day occurred when an elderly
- gentleman lost sight of his glider and it went into a vertical dive. A friend
- of mine yelled for him to pull up but was not heard, so he sprinted over to the
- guy, yanked the control off him and just pulled up. Talk about lucky, this
- plane just leveled out inches off the ground (no kidding) but unfortunatly the
- plane couldn't handle the gees, it was really moving, and one of the front
- wings blew off taking half the tailplane with it, and luck still being with
- this guy, because it was so close to the ground all that happened was that half
- the plane tilted up and it slid to halt with no further damage.
-
- For those of use that fly off bungees and winches you've probably seen what
- happens when there is too much force for the plane to handle (ie high wind or
- too much tension on the winch). One day a whole lot of people from a local
- nightclass group were down flying their new gliders, when all of sudden there
- was this little cracking noise, followed by a whistling them a loud thud. The
- poor fellow walked over to the remains of the fuselage as the wings fluttered
- down and picked up the pieces. Not to be outdown the rest of the group decided
- to keep on flying, not realising that their gliders couldn't handle these
- conditions. One after another they fell out of the sky on the launch, some
- still with the wings attached but folded, others with half wings (one guy
- attempted a landing with only 3/4 of a wing, but didn't quite make it - I know
- how hard this is as I've done it myself). The same day as this I got quite a
- bad scare with my glider on the launch, it decided that it would do sea-gull
- impersonations and flap its wings a hell of a lot, I thought it was going to
- fall to bits there and then. This doesn't bother me any more but it's good to
- watch the expression on an experienced pilots face when you go into a dive to
- pick some speed up for loops etc and the wings start to really flap!
-
- By the way for those that find that the bungee hasn't released it is possible
- to land with it still attached, I've done this many a time, mainly when I'm
- doing stupid things and it wraps around the wing on release. Just fly tight
- circles, you can increase these as you get lower, and watch out for a stall as
- this can be disastrous with a line still attached.
-
- I went flying a month or so ago with my new slope sloarer, its 3 years old and
- has flown 2-3 times, I'm not use to ailerons or slope sloaring really and
- managed to plough it into the hill I was flying off - I think I'll stick to
- kayaking for the rest of the year because I don't fell up to fixing it before
- winters over.
