'Is this the box the JetRanger came in?' First flown on 23 January 1961, this bizarre-looking helicopter was powered by a vertically-mounted turbine with a compressor that fed air through the rotor head to ejectors at the tips. The shrouded tail rotor was later replaced by a conventional one. Apparently it was not just a technology demonstrator since five passengers or two stretchers could be accommodated and the doors could be removed for utility purposes. Development had stopped by 1963. The aircraft does not appear to have carried a registration or serial.
