Flame,
Thats an easy one to answer. I have only ever worked on fighter aircraft so there is one pointy end and a blunt end, and the blunt end is invariably extremely hot, and noisy.
Also the pointy end generally has lots of other pointy things pointing in the same direction. Finding the right end is so much easier!
Think we should wait til the weather is a little warmer for the picnic but the offer still stands...lol!
