If I do pursue that IR option I will delight in setting fire to the nylon when I am done so I will be able to report on how well it went. Might even put it on Youtube
I recommend you're not wearing it at the time.
I'm not too worried about personal protection from fire in the air, especially as my aircraft is fuelled with less flammable Jet A-1 and both engines are located well behind me. It's maximising the chances of escape from the aircraft in the hopefully very unlikely event of an accident that I'm more concerned with.
In addition to our burned crewman I mentioned, I will never forget the thought of a friend of mine who perished in a crashed and burning biplane in 1989, only about two miles from where I'm sitting now. His girlfriend also suffered very serious burns trying to pull him out. Before the accident I was the last one to sit in the front seat he died in. Had she been wearing more suitable clothing she might have been less badly burned.
