{By an image of a Lancaster Bomber:}
Tests conducted by the Road Research Laboratory against model dams built on this site during 1940 - 42 assisted Barnes Wallis in his development of the bouncing bomb (Upkeep), used by No. 617 Squadron Royal Air Force to breach the Ruhr Dams 16/17 May 1943.

Site: Sir Barnes Wallis - Harmondsworth (2 memorials)

UB7, Moor Lane

This marks the site where Wallis's water-skipping explosives were tested on models at the Road Research Laboratories. Tom Long sent us this 1946 map which shows the Road Research Lab buildings a little to the south, on the Colnbrook By-pass, to the east of the 4 houses that are still there, surprisingly since Heathrow airport wiped out most of what's shown on this map.
