So Blacksheep do I understand it correctly with centralised servicing when there were multiple squadrons on the station the ground crews were consolidated and serviced all aircraft irrespective of squadron.
At Finningley on the OCU we had 'A' and 'B' squadrons with 'A' flying the B1's and 'B' the B2's. Whilst I was there there was never any crossover of ground personnel between the two. This was 1963 to 1966.
Was amused down in Sharjah when the USAF phased a couple of Phantoms through. I think it was a Herc that turned up and disgorged hundreds of ground crew to service them. We just did anything that dropped in - Beverley, Javelin, Argonaut, whatever. We even had a commercial passenger flight call in with radio problems. Fixed that to. I think it was an Arab airline, so we organised two tin cans and a bloody long piece of string.
