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

One of the first measures to reduce costs was to minimize refueling planes in foreign airports due to higher jet fuel prices. Aircraft were fueled in Poland to the maximum possible take-off weight. As a result, the crew used the full length of the runway. Conversely, they had a relatively small amount of fuel in reserve on the return flight, which sometimes forced them to land in bad weather. Flights with a maximal take off weight
