VC10
Bristol 188, a stainless steel skinned plane to test the heating effects of flying above mach 2. Unfortunately mach 1.8 was the most they got out of it

Not a harrier OR a P1127, it's a Kestrel (OK probably splitting hairs

Not a Lightening prototype, it's the one & only Shorts SB5 - an aircraft designed with a Lightening plan form to test the low speed handling (note the non-retractable undercarriage).
BAC221 - modified from the Fairey Delta II prototype.
Gloster Meteor - this one has an additional "prone pilot" cockpit to test if flying a plane while lying down was a good idea.
Fiesler Storch - one of the first proper STOL aircraft, it would fly down to 35mph & was used to rescue Mussolini
I was waiting for someone to say "Lancaster" - it's not, it's a Lincoln, a re-designed Lancaster, bigger, faster, heavier. Designed to bomb Japan from the Pacific island airbases.
Yes - TSR2, probably the best bomber the world never had. Deliberately scuppered by the Americans because it was streets ahead of anything they had.
Saunders Roe SR53, Rocket fighter, the small intakes behind the cockpit lead to a small "get you home" jet engine, so this was like an ME163, only more sensible.
Hunting jet flap research aircraft - another one that could fly at 35mph. It made it's own lift by blowing engine air over the flaps
Boulton-Paul defiant. Looks like a Hurricane & when fist sent up in the battle of Britain was spectacularly successful, Jonny foreigner didn't expect a Hurricane to fire on him from the side / below / in front. Unfortunately after about a week Jonny foreigner caught on & attacked them from underneath & being a ton heavier than a hurricane they didn't have the manoeuvrability to respond.
Messerschmitt 262, the first jet fighter in service, that's the gun bay open there - it could ruin your whole day.
Yes ME 163, not intended as a suicide aircraft, but often ended up that way as if the fuel didn't explode on touch-down, it leaked & dissolved the pilot where he sat.
Vickers Valliant - first of the V bombers, didn't take well to the change in role to low level, cracked & fell apart
& finally, couldn't resist this one

Not something BMW make a lot of in their advertising!
