Prototypes.....what airframes are still with us?
 

..of the top of my head.
Mosquito,
Concorde,
Tonka,
747,
What else is still out there?

Hawk I believe, using prototype in the sense of 'first one'.

EAP, now the Typhoon.

Boeing 367-80 also known as 707
The first 727 still survives as does the prototype 737

A research vehicle rather than prototype, but how about the Short SC.1 in the Science Museum, London. It is currently hanging on a wall on the ground floor, not in the Flight gallery on the top floor.

A320 MSN 1 is still flying.

Gloster E28/39
 

Not quite a prototype, but still an interesting aircraft, still earning it's keep.


BAe 146-300 G-LUXE, converted to a 300 series after build

MD11
 

N601FE was the prototype and is still flying with FedEx.

I believe there were 3 aircraft in the test programmer, N602FE was another, third would have been a pax config?

XS230 prototype JP5 still flying i believe

The very first Ryan PT-22 flies out of Old Warden, owned by Tracey Curtis-Taylor.

Fairey FD2 BAC221 TSR2
 

FD2 at FAAM
BAC221 at IWM Cosford
TSR2 at IWM Duxford

Avro Vulcan at Cosford?

I seem to recall that the prototype Heron still exists in Australia.

G-LUXE, formerly G-SSSH was the first 146 to fly. Fairly uniquely, she is both the first and the last off the production line, as it went through -100 prototype, -300 prototype, and the only -301, which she still is and very successfully.


EAP was a research aircraft. But the first Typhoon prototype, DA1, is in the German Air Museum in Munich.


I've had the privilege of flying the prototype Easy Raider, Escapade, Savannah(UK), SkyRanger (UK) and X'Air(UK). Of those, the Easy Raider prototype, G-SRII is still listed as having a permit, as is the first UK Savannah G-CBBM which was later the Savannah VG prototype, and the SkyRanger prototype G-CBIV. I don't know about the other two apart from their permits are several years lapsed.

G-ASAL Bulldog prototype
 

G-ASAL the prototype for the Bulldog was restored and is, I believe, still flying out of Prestwick.

My first experience with a stick rather than a yoke and after the first few seconds of PIOs on takeoff which almost literally scared the **** out of me, I absolutely loved it :)

The one and only Bullfinch was still flying the last I heard.

There are a couple of TSRs about but neither are the very first one.

The Wright Flyer still exists.

The first 757 and 767 both still exist, although not in their original configurations. The 757 has a funny wing on the top (part of the F-22 project), while the 767 has a massive tumor on top (which housed a cryogenic cooled infrared sensor as part of the "Airborn Optical Adjunct" program).
