I see my old gliding instructors occasionally (84 – 91), and my IMCR/NR/TD conversion and AOPA aerobatics guys are still around. I have lost touch with Tony Morton (ex Truman aviation) who did my gliding to PPL conversion in 91, but he is probably still around (any body know – he took up teaching IR’s up north I think).
That makes about 10/11 still with us for sure, but some are getting on a bit now. All are still instructing or have retired into LAA coaching.
