  1. I am surprised they did not try and sell the helicopter to the army. A fleet of them landing anything up to a regimental size group where ever they were needed would be of huge importance. The autogiro you show at 1:35, the Avro Rota C-30A, was one of those unsung heroes of the Battle of Britain. They were used to calibrate the radar so they could work out the hight of the incoming German bomber raid. The radar operators needed something which could fly as slowly as possible at the same altitude as the raiders. I believe one thing the would do to reduce their speed was fly into the wind which could bring them virtually to a stop as far as ground speed is is concerned. All this while being unarmed and with German fighters about.
