The Bristol 173 was intended as an airliner helicopter but G-AMJI was tested by the military as XH379 from September 1954 until September 1956, just before it crashed. We found that the Big Ben was in scaffolding from early 1955 until the spring of 1957 to repair damage from Luftwaffe bombing. The last BEA helicopter flight from the Waterloo Air Terminal was on 31 May 1956 but we are not sure when the heliport closed. Photo from: Nationaal Archief (Netherlands)
