Our Kiwi pilot from Wellington to Picton lived up to his national reputation of dry humour. Our little plane was being buffeted by some turbulence and there was a knocking sound coming from one of the doors. I told him about the noise and asked him if there was something wrong.
"Oh you can't usually fly this thing with one of the doors open", he said matter of factly. "Try not to touch it and make sure your seatbelt is really tight."
Never did find out if he was joking.
