Isn't the flame-retardant property of flightsuits and gloves a feature of the fabric itself, not something that gets washed away, or vaporized in the dryer? It is not impervious to flame, like asbestos or something, but has to get very hot before it burns up and burns into ash, vice melting.
I used to go glove free in the -46 whenever I could, but since I transitioned to the V-22 I got used to the feel of gloves. Especially now that there's a thumbwheel on my left hand with 1/4" deep knurling on it, I need a glove there, and one-handed glove action, a la Michael Jackson, just isn't cool. The only exception is when I teach a sim, since the instructor control screen is a touchscreen above the right seat, which, for reasons I can't quite comprehend is only sensitive to bare hands, not gloved ones.
