nipva: excuse a similarly-aged aviator, but in the sixties rotary was still at Tern Hill. I was there in '66. Sioux (Bell 47) and Whirlwind.
. Indeed so - IIRC it was '75 or '76 that rotary training went to Shawbury. By then - I think - the Siouxs had gone and it was straight through Whirlwind, except CFS(H) who flew the Gazelle.
Sycamores were still used up to the mid-60s I think, but had gone before I got there in '69.
[Edited to add:
a quick Google suggests Sycamores were still at TH in '65/'66, so looks as if Herod just missed it.]
