The only time I sh@t myself (so Far):
Middle-aged PPL student prior to first solo practising circuits. We landed on RHS of (wide) runway at Cranfield. He had just learned to ski, and started pressing the right pedal to take us towards the centre of the runway. Not a word of a lie, that 152 was on two wheels, and I don't mean the landomatic mains. After that , leaning the mixture in the circuit is a piece of cake, or trimming the wrong way then letting go of the control yoke. Happy days....
