Heathrow Airport and continuing construction work, Harmondsworth, 1946 | Britain from Above
In this 1946 aerial shot you're looking down runway #1 aka10L ( now 27R/09L), #3 is already effectively disused ( it ran through the location of the planned central tower) and in use as a parking ramp for aircraft and in the distance the first of the second triangle is built across runway #2 (23L/05R,which did have a long and useful life)...........and it was all determined by the location of the sewage plant in the foreground which Middlesex County Council wouldn't move :-) ......and over time Heathrow got 3 runways in the NW/SE direction where the wind is least common
