Hello ,I’m back (perhaps for the last time!)

As it was written in FLIGHT magazine,if the hinges was on the trailing edge,the airbrake opened like a suicide car door!It seem incredible but I have discovered a picture of the MC DONNELL XF-88 with the first airbrake model tried open!

This airbrake have had the same effect described by R Beamont on the P1 and have been also modified latter.

Only an examination of the WG760 at RAF Cosford could confirm and perhaps showing the hydraulic jack (locked for the further test flights).

Many thanks Wokka Bob….
Your explanation is very accurate…to take my curiosity ended but not my frustration!
Yours sincerely.

Yes you are right…
I rewrite the Flight description “another airframe alteration in the P1B is that the speed brakes have been redesigned and relocated.Originally they were mounted on the rear-fuselage sides just ahead of the jet nozzles…each brake was hinged at its trailing edge”.
I think this is the part corrugated and heavily riveted visible on your second pictures…

So I haven’t found a photo showing them open even on ground or in flight!
