Ron, 2ANS used both Varsity and Valetta and the Pig - the flying class room for night astro using the Mk 9 sextant. That phase lasted 8 months. 1ANS used the Varsity and the Meteor 14. The Varsity when used for astro had a special plate put in place instead of the astrodome and we used the Mk 2 perisextant. Th change over was done in flight!
The meat box phase lasted about 4 weeks and was quite sporty with high level Gee rapid fixing, unpressuried (or maybe 25k) at levels arounf 39k. The meatbox was not cleared for aeros so we never experienced loops and rolls etc (we were told)
