The Jupiter man powered aircraft project had been running for some time by the time 120 Entry became involved. In fact, most of the construction had been completed by the time we began our training. However, encouraged by Flt Lt John Potter, our Aerodynamics teacher at "Schools", a number of us did participate. Our first tasks included application of much of the the Melinex skin, moving Jupiter to RAF Benson and then reassembling her. That process alone took many weeks and many evening and weekend trips to Benson in the old PSI mini-bus. We were then totally involved in all the taxi trials, leading up to the first flight by John Potter on 9th Feb 1972. Being of suitable small stature, TA Davies was often used to taxi the aircraft on the down-wind legs and was even encouraged to "hop" the aircraft once or twice, allbeit tethered to runners at each wing tip (see photo above of Davies receiving "orders" from Flt Lt Gillchrist). Sadly, the coveted Kramer prize proved elusive for the Halton team, probably because the aircraft was of quite a robust design compared to the eventual winner.
