Just watched the safety slideshow on that website....hmmm
The state of the leather gloves back up exactly what happened to mine...
I used to glide with the space cadets, and we were issued with all the RAF kit, including the white posey leather gloves. At the time I had a sha99ed out Honda 90 as transport(yeah, young wild and free
)
Anyway, the exhaust fell off one day as I was on my way to the gliding school. I just happened to be wearing my flying gloves, and not thinking, I picked up the remains of the bl00dy hot exhaust....the gloves immediately shrunk and looked exactly like those in the pics, and were a bu99er to get off-but they were still better than bare hands.
As a commercial balloon pilot I wear thickish leather gloves, but having seen the pics, I might well try a pair of Nomex ones. Our problem is that they've got to be liquid gas proof too, as if we have a leak, the propane comes out at -42°C and I suspect the nomex will let that through...
Food for thought though...
