TR0721 : Listening Ears

near to Lydd (london-Ashford) Airport, Kent, Great Britain

Listening Ears

These are concrete listening ears built in the 1930s (before World War 2). Airplanes flying across the channel could be heard by observers positioned near these "ears". Whilst they worked when the wind was favourable, the speed of sound v the speed of aircraft meant that they gave only a few minutes notice of impending attack. Annecdotally it was said that observers could hear the "Golden Arrow" train leaving Calais. They were made redundant with the advent of radar in 1938.
