I agree with the date error. In Feb 71 there were, as far as I remember, only the 2 JP5s for HRH. The rest of the line was still JP3s and 4s, so this film must be a fair time later. Even Haraka still looked like a boy..... Also, not a flight cadet to be seen, begging for cast-off fags and beer dregs from the super-rich student officers. From memory, the last flight cadet entry would have graduated in Feb 73?
