Hillingdon London

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.
