May I remind Rocketeer that the work he does now was carried out by the AFEE (Airbone Forces Experimental Establishment) until 1950 and not the A&AEE .
Likewise A&AEE didn’t do any testing on the assault gliders like Horsa and Hamilcar. (RAE and AFEE)
The military also had there own development units, and to a lesser extent still do.

Consider myself reminded thanx:)…but I did come from FW old chap!!!:)
