I think you're right, Haraka - some time in the Lent Term 1973?
Some very mediocre cars in that photo. Not student cars as we had to park at Mitchell Block - but did our QFIs really drive such dull vehicles?
I only flew with the Underpants Tester a couple of times - a '9 day check' on 3 Mar 73 (then a couple of solos the following day) and an 'EEs' trip on 16 Apr 73, followed by 3 solos over the next 2 days sweeping imaginary Huns from the skies of West Berkshire!
Great times those were.
