I totally agree re nylons etc, there was a WRAF went down an emergency slide at Brize during a test and her knickers welded themselves to her bum, poor kid.
When I refuel my car even on a sweltering hot summers day, I always wear a thick cotton jacket, simple reason really, a good friend from home was involved in a flash fuel fire, and after I saw what he went through I was determined it wouldn't happen to me, it makes me wince when I see people refuelling on a hot day in a skimpy teeshirt.
