Amusing trainee comments!
I started my flying career in a 3-axis microlight several years ago, instructed by a gentleman famed for his down-to-earth view of aviation, and life in general. I paid for a (slightly nervous) non-flying friend to have a flying 'experience' with said instructor. After the briefing, he was strapped in, now looking more anxious. He then said to me, wide-eyed, that he was worried, as he could smell petrol..... Overhead, the instructor said 'Son, time to worry when you Stop smelling petrol'! Nearly fell over laughing!
