I was there for a few days in mid 1961, when it was the Aero Med Training Centre. We were given some fairly harsh training as were going to a relatively high altitude and had to wear the Taylor Helmet and pressure jerkin. I recall that we were taken from 25k ft to about 50k and taken back down to 25k. Most of us finished up with a strange red spotty rash on our torsos and one or two ruptured their eardrums but didn't know about it until they took their helmets off and had blood running out of an ear. There was also the unalloyed pleasure of wafts of Ruddles based carbon di-backside to jolly things along!
