This is a fascinating newsreel of the building of London Airport in the fields on the edge of Hounslow Heath at Heath Row.
There’s something slightly terrifying about watching the coming of the jet age to London, “And the landscape was changed and the past obliterated”, the voice-over declares in a cold, officious tone. The past wasn’t really obliterated as much as they’d like to think, the rivers Crane and Colne will continue flowing through the terrain long after we’ve moved onto teleportation as the best way to get to Marbella.

It’s interesting that no mention is made of the archaeological finds of neolithic settlements excavated during the construction of Runway One. Maybe they were too high on jet fumes to notice.
