Well, one dangerous moment was when I was sitting in our solar powered speedboat. The minutes before this all happened, I successfully made it through the classification trial course. While slowly drifting around, I heard a kind of muted bang. For some reason I knew it had to be a problem with the Li-Ion battery pack. Felt a quick heat-wave moving from my back to the front (escaping the 'hole' in the fuselage where I was in).
Getting out of the 'cockpit' usually took some time, but this time I bailed out into the water as quick as possible.
The moment I was in the water, I saw a big flame coming out of the cockpit where I sat just moments before.. You could hear the Li-Ion cell strings blow one by one. The minutes after, the whole thing exploded and burned up...
Another occurrence from which I learned a lot:
One day we where flying sailplanes from an airfield on top of a hill. This is great for many reasons, and also impressive at take off. After being launched by the winch, I noticed a very nice cumulus cloud. Good cumulus clouds almost always have good thermal below them, that's why they are interesting for gliders. So flew straight at this cloud.
About half-way I started thinking that it took longer to reach it, than I expected. I made a turn to look at the field behind me, and got a bit 'shocked'.. the airfield seemed to be very far away...
Started gliding back, once I reached the landing circuit, I noticed I never had enough altitude left to fly a full circuit. I knew that on the final leg (downwind the mountain), there was a kind of 'invisible' rotor in the air, a big turbulence that would pull your plane down then up.
So... I wasn't anywhere near the required normal circuit altitude, much lower, so I decided to land half-way the airfield, skipping the final leg. This is a normal procedure, but one of my first times doing this solo. In a glider you only have one chance to land (like the space shuttle
) - no go-arounds - so planning ahead is important. Landed safely, but learned one important thing: Always keep an eye your airfield, until you have enough altitude for greater distances.
