I would say Farnborough can claim to be an airfield, it was a field cleared for air operations!
The balloon and kite activity were alot more than part time experiments, it was part of military flying, and the area was designated for their use (Laffans Plain being just across from Aldershot).
As mentioned, Cody made his flights there in 1908 and fixed wing flying (in partnership with the army) carried on thereafter.
I fail to see how any other airfield can claim to have operated longer.

Edit, Balloon Corp arrived in 1904, and 2 Sqn, the first fixed wing Sqn of the RAF (then RFC), operated fron Feb 1913.
Its amazing how many Squadrons were at Farnborough from 1913 on.

Vampires and Venoms well known for doing that, and along with the bang and black acrid smoke from the starter cartridge, all very exciting!
Penzance S-61s always seen to do it on the first start of a dewy morning, much to the consternation of the passengers!

Here at St Athan (where they are all serviced) they say an end date 0f 2012, but I know that date keeps being extended! Both C.1ks and K.3s are meant to retire together.
They are favourite of mine and I never tire of seeing them fly in and out of short runway here, or that lovely Conway whine.
Truely a remarkable aeroplane, with none lost in militay service.

There was a Blue Streak in the Science museum in London, I assumed it was still there?
I’ve seen that Ch4 docu on our rocket programme, very good footage and interviews with people who worked on it.

Cracking photos there!

Got to say though, I am anti hanging the aircraft and cramming them all in, this trend seemed to have started at Duxford with the super hanger.
how are you supposed to get a decent pic of the York or Hastings? Im glad I saw all exhibits when they were outside or parked properly.

Is the Brittannia and other airliners still there?

BTW there are two types of caravan these days, the one I mentioned above which is a fully self supporting truck, manned for arrivals and departures and back up to air traffic control. The second is usually a trailer or towable affair which is used when the main air traffic control is closed or unmanned, usually for glider or trainer aircraft use. This has been around for a while and I wonder if this is what is shown in the picture taken at Leuchars.

Also there was the GCA / radar, PAR, and standby local (usually fixed and semi burried) caravans – they’re another topic.

I assume then the fairings were whitcomb pods similar to those on the Victor mk2. If so then they were a way of “area ruling” an existing airframe to help reduce transonic drag.

Yes (Kauchman carrots), and somewhere to but the main undercarriage units without cutting into, and weakning the wing main spars. Vital for its low level role.

The Shawbury Sea Harriers are being moved to Culdrose, some already there.
Some nice examples at Predannack for the fire school aswel.

The St Mawgan GR.3 was in a right state when it left, even if it was ok when it arrived!
