Testing The Sound Mirrors That Protected Britain

  • Published on: 06 August 2018
  • Over on the RAF Starrship channel, I'm talking about the history of radar: https://youtu.be/VDC_RCh0ws8 - but over here, we're testing a 90-year-old piece of technology that was meant to be part of Britain's air defence. The Sound Mirrors, on Romney Marsh, were built in the late 1920s as a way to amplify the sound from aircraft engines over the English Channel. We're flying a bit closer than that, with a drone.

    I've wanted to make this video for literally four years, and - thanks to the RAF team - all the pieces finally came together. Do go check out my history of radar video over on their channel!

    apparently they had these on Malta during WW2 and they were so sensitive they could pick up the noise of aircraft engines starting up on the Italian airbases in Sicily, over 50 miles away

    I've been to Romney marsh loads of times, why have I never heard of this before??

    At the science works museum in Melbourne Australia, they have something similar on a smaller scale where they have two dishes facing each other roughly 100m apart and when you speak into it the person at the other dish will hear it. It鈥檚 quite cool

    Old satilite dishes can be lined( coated) .and used to comunicate .smply point two at each other and stand listen speak from focal point..

    "Humanity" didn't invent radar, Sir Robert Watson-Watt did. "Humanity" without the insights of a tiny number of inventive men (and virtually no women) would still be living in caves.

    There is an almost identical acoustic mirror built near Ba魔ar i膵-膴ag魔aq in Malta. It is known locally as il-Widna.

    Why has it not been demolished?. It's such a strange thing with humans, we leave our old garbage all over the place.

    That is absolutely brilliant. Really, a clever way of detecting aircraft before it's coming. Sure, radar was invented, but this was ahead of it's time. If something had happened that required this system, they would be the only ones in the world that had it, and it's super well thought out, too. Amazing.

    I love your videos, but you cannot reasonably compare a wavelength and a surface. That simply is not homogeneous !

    Why do you need permission? it's just a bunch of concrete, why flying a quad would cause any problem ? I though you would fly a real plane in low altitude, that's why the permission.
