“The Fighter Jet Take-Off Platform was a concept platform that would rise vertically from the ground, and allow an aircraft to take-off from its back — allowing planes to operate from small airstrips or narrow forest clearings.
English Electric developed the P17A jet to fulfill the purpose of a tactical strike and reconnaissance jet, and rather than attaching a heavy vertical take-off and landing system to the aircraft, they collaborated with Shorts, who created the P17D — a platform that would stay steady above the ground and allow the P17A to take-off from its surface.
With no less than 56 jet engines, the P17D gave the P17A the desired effect of being able to take off from tight spaces. On its own, the P17D would also have been able to fill the role of a VTOL freight transport, able to deliver equipment and supplies to less-accessible locations…” (via)
“The ‘Jumping Jeep’ was a concept reconnaissance vehicle capable of leaping over obstacles - a 4x4 transporter flanked by 12 vertical lift fans, whose angle could be adjusted dependant on the situation - allowing the jeep to overcome enemy barriers.
Developed by BAC Warton at the request of the British army in the 1960s, the design was an attempt to adapt vertical take-off and landing technology to vehicles and was developed with the Ministry of Defence’s Fighting Vehicle Research and Development Establishment.
The project was cancelled in the mid-1960s, due to assessments that production of the design would be too expensive” (via)
"The Intercity Vertical-Lift Aircraft design from the Hawker Siddeley company was an attempt to bring vertical take-off and landing (VTOL) to commercial aircraft, to allow airlines to put airports amongst densely-populated cities, open up more direct travel for passengers and to cut down on the amount of space required for airport runways.
A number of designs were drawn up over the 1960s, looking very similar to our passenger planes today; however featuring rows of lift fans on either side of the body of the plane.
The project was eventually dropped after it was decided that together with the cost of fuel required to fly the aircraft and the extra load from the frames housing the lift fans, combined with the weight of passengers, could lead to instability in flight…” (via)
