Ref: RAF Valley.
Was the Hunter / Gnat / Whirlwind situation very much different from what is being proposed in the form of Hawk / Tucano / Rotary? Valley appeared to operate well in the 70s.
Could Tucano operate primarily from Mona in the same way that DHFS initially proposed to operate a Squirrel Sqn from Tern Hill. ie First flight out of Valley lands at Mona, and last flight from Mona returns home. Thats what portacabins are for if the support real estate is missing at this time.
I suppose closing the Vale of York and firing up Llanbedr is taking the Pee.
