I am told that the Vampire Trainer cockpit-front fuselage was heavily indebted to the Mosquito, but while I know the Vampire, I don't know the Mosquito, so I don't know how true that is.
Royalistflyer,
You are correct. The Vampire T11 forward-fuselage is moulded plywood, built in the same manner as the Mosquito's fuselage. The remainder of the aircraft is of conventional aluminium construction. I suspect the Vampire cockpit is slightly wider than the Mosquito's, since the seats are side-by-side, whereas the navigator's seat in the Mossie is set back to avoid rubbing shoulders with the pilot!
I suspect this must have been the only pressurized wooden jet.
