Hawker Siddeley P.1127 Hawker Siddeley P.1127 The Hawker P.1127 and the Hawker Siddeley Kestrel FGA.1 are the experimental and development aircraft that led to the Hawker Siddeley Harrier, the first "vertical and/or short take-off and landing" (V/STOL) jet fighter-bomber. P.1127 development began in 1957, taking advantage of the Bristol Engine Company's choice to invest in the creation of the Pegasus vectored-thrust engine. Testing began in July 1960 and by the end of the year the aircraft had achieved both vertical take-off and horizontal flight. The test program also explored the possibility of use upon aircraft carriers, landing on in 1963. The first three
Musk electric jet Musk electric jet The Musk electric jet is a jet-powered supersonic electric aircraft concept by entrepreneur Elon Musk. Specific design concepts for a vertical-takeoff-and-landing supersonic electric jet were first made public by Musk in 2014. The concept includes a large percentage of the aircraft by weight being made up of high-capacity batteries and significantly decreasing the amount of aircraft structure devoted to control surfaces, depending to a greater extent on "gimbaling the electric fan" for control of aircraft attitude. Musk had publicly mentioned the supersonic electric jet idea as early as 2012. Initial public discussion of the design concepts behind
