My god, that was hot work, trying to get some rest/sleep while
lying back in the midrest seats alongside the open overwing
hatches listening to the hellish pounding of the slipstream
there. The bunks were unuseable due to the heat. You guys now
have it easy in airconditioned comfort!...

Nomex is well known in the oil refining industry as being hot in the
summer and cold in the winter. It only protects against flash fires up
to about 900F AFAIK and you ain't gonna make it if the fire is really
bad. Personally I always preferred cotton clothing when I was a plant
operator and still wear cotton and wool by preference. Hopefully my
Nomex coveralls are hanging in the closet forever. VBG

Y'know, this is a favourite subject of mine. We wear Nomex for
years and years with all the attendant discomfort that it gives
us just to protect 'someone' for a few seconds of 'flash fire'
maybe. Seems like a silly thing to do, it's like we provide a
'fireguard' for every a/c engine start when it'll maybe do some
good on some start ten years in the future. I've likely started
thousands of aircraft engines and NEVER had an engine fire on
start, moreover, I've never even seen one. That spread out over
26 years of service. Never even SEEN one, let alone HAD one
myself, let alone had one myself which was put out by the fire
guard!!.
Seems a huge waste of manpower to me...yet it was drilled into
us...NEVER START without a fire guard!...and I did once too,
still feel a twinge of guilt...
