They were used in the early days at TTTE.
I was doing a post primary* ground run and one of the checks for the riggers was to carry out a func of the bottle. A short time after I had operated the system there was mega fumes in the cockpit. With eyes weeping & stinging and throat burning, I shut down and vacated the cockpit feeling quite wobbly
.
Turns out that a pipe was leaking and the liquid had contaminated the fairy kit giving off nasty fumes.
Despite my protests saying that I was fine after a gallon of water, I was taken up the med centre, in a meat wagon, for every test in the world.
Still, I got the rest of the day off.
