From the link posted by Glojo:
Prototype ZZ402 paid a brief visit to Iron Duke just before Christmas, when pilots and technicians tested some of the basics – could the flight deck recovery system pull Wildcat into the hangar (yes it could), did Wildcat fit in the hangar (ditto)...
Was it really not possible to know for sure whether the aircraft would fit into the hangar until it was actually tried with the real aircraft?!
I thought the Wildcat was a WW2 Fighter
So was the Typhoon...?
