The first manned airborne ejection seat firing took place on 24 July 1946 over Chalgrove Airfield, Oxfordshire, in a Meteor, piloted by Bernard Lynch; the first dummy ejection had been 10 May 1945 over RAF Oakley in west Buckinghamshire (today near the M40); on 13 March 1962, the first in-flight rocket-powered ejection took place by Peter Howard, an RAF doctor based at Farnborough's Institute of Aviation Medicine in Meteor WA364 at 250 ft over Chalgrove, with the rocket giving a maximum force of 16G. The Miles M.52, designed at Woodley Aerodrome in Berkshire by Miles Aircraft, was an advanced design of aircraft which had the innovation of the flying tail or all-moving tail also known as a stabilator; this would solve the problem of stability and aircraft control at supersonic speeds, and its design was taken wholesale into the American Bell X-1, the first supersonic aircraft.
