Right I think I can see why there may be possibly some confusion about this, the plan (which appears in St Eval books) posted by Dr Strangelove incorrectly lists ‘I’ as the Cannon Butts, its not, they are in fact just to the west of of the frying pan dispersal (where the aircraft would be sat) and ‘I’.
The official AM site plans from a building survey in 1944 shows ‘I’ as Extra Over Blister Hangars with that stub road running to the upper left spectacle dispersal.

Some slightly sad news is that the 1960s era NAAFI complex is due to be demolished, not the most beautiful building on earth I grant you. http://www.thisiscornwall.co.uk/Centre-Defence-building-handed-village/story-13481528-detail/story.html
The squash/racquet courts is under threat aswel, which is sad, as far as I’m aware it is one of only two of the wooden version ever built, and the last one surviving.
I also see that the lovely Officers houses and doctors surgery have been refurbed and up for sale, a snip at £300,000!

Hmm I can’t view the pic that well on this tiny laptop, but I would kinda say you’re both right, ie the Blister is definitely where you think it is Nick (you can see the white painted – as a daymark – church tower to the right), but the Wellingtons are possibly on or near the dispersals suggested by Strangey.

The location deduced by Nick, and backed up by the RSP, is item ‘I’ in the basic plan that the good Dr has provided, is there a key with that plan to tell you the building use? The RSP gives building type, construction, and number but not the use.

He certainly can on R4118.

Quick and concise, thank you:)

I can absolutely assure you Bomberboy that the St Eval RSP indicates a Double Extra Over Blister Hangar (longer span and double length), blg no.120, on the precise location of Nicks and my link.
It is not on the Cannon Butts track or hardstanding, but immediately east of it, it is to the north of the peri track and just west of the church, as Nick has deduced in his first post.
I’ve known buildings not to be annotated on RSPs, but never known buildings show up on them that weren’t there in reality!

The area concerned is these days owned and occuppied by a construction/salvage company that have all sorts of major plant/diggers etc and I would advise that any potential visible marks in that immediate area on modern day satellite images that do not tie in with the existing actual known structures should be viewed with an amount of suspicion.

I do know what I’m talking about, I have spent a long time researching airfields and am local from the St Eval/Mawgan area, I also know about the pitfalls of separating modern works from original, both on the ground and in imagery.;)

Looking good, must be a quite a collection or rare US cockpits you have there now. Do you still have the C-119 cockpit or am I getting muddled up with somewhere else?
Will the 26 be retaining it’s K Vietnam markings?

He was probably the first British pilot to break the sound barrier, test flew the high-speed de Havilland Swallow after the death of Geoffrey de Havilland junior…

John Derry is recognised as the first British pilot to break the ‘sound barrier’, doing so in the DH.108, on 6th Sep 1946.
Looks like it will be an interesting talk though.

Believe it or not I don’t have that book, but I will look at some of pictures and I do have a copy of the airfield plans with building keys.
