I remember only to well, that having finished my Varsity course in 1971, and holding at Oakington, I was 'volunteered' to go to Farnborough to test G suits.
We (there were 2 of us) were 'chosen' since we were big aeroplane men and therefore not conditioned to strain like hell when pulling G.
The first day we were kitted up in a G suit and placed in the centrifuge, (the well known vomit comet) and given a button to press and a light to look at. The machine was set in motion and when the light faded (usually around 3.5g with the suit inflating) we had to press the button. Sometimes the suit inflated and sometimes it did not. However, strict instructions were given not to tense up and just to let the suit do the business!
Twice a day for a week and then sent back to base. No one told us the results, but surely G suits were in service before 1971, and if so why were we there being sick twice a day.
Twice a day for a week. Still it was an experience.
