Yeah, sorry about the resolution on the other ones, however the advantages of the IWM shots are the official nature they convey, the added details which are sometimes on the site, the fact I can tie the 464 ones back to an ORB entry, and sometimes they are stuff one doesn't see elsewhere.
There's another fuzzy IWM shot I'm going to post later of 21 Squadron Mossies raiding an occupied airfield in daylight - smoke and dust rising from bomb strikes, detonations going off in the background, a 109 parked on the field and a trailing Mossie banking away with doors open - speed, daylight, action all come through.
(Heheheh, can't see the exhaust stubs on the trailing aircraft though...)
Naturally, IWM wants $$$ for the full-size versions, my Mossie budget doesn't run to that.
