1) Bashing my head on the high Cessna wings. A lot. And I still do it.
2) Missed the foot hold on the spar of a 172 when checking fuel. My foot slid along the spar, I fell off and smacked into the tarmac. That one hurt!
3) Pulling the aircraft with a towbar that wasn't properly anchored. It flew off and I fell backwards and thudded into the taxiway.
And why do all these things happen when there are lots of people watching?
