As I’ve recently been on e-mail with an old friend from 20 Sqn in Singapore, in the context of a Reunion, the potential attendance list was amazing! And ... the aircrew back then (late 60s) had a high proportion of early 20s on their first squadron tour. How did we achieve that back then, without sophisticated simulators, if we can’t do it now? My aircrew mates had probably been in for 3 years or so, and there they were on Front Line sqns whacking Hunters, Canberras and Lightnings around the tropic skies.
Aplogies for old bloke input
