Found this and thought it plausible. I mean there are amateur astronomers scanning the skies, HAMS monitoring all manner of radio waves, why not folks having their own sonobuoys and listening to the oceans? I doubt it got leaked from the US Navy, but that's only a matter of time before a leak or actual release. Maybe another friendly country in the North Atlantic; Canada, Greenland, Iceland, The U.K.?
The static right after the bang is from the sudden release of air. I was surprised by the echoes, but it makes sense. Look at what happens when a tsunami occurs and how the motion can circle the globe.
This guy (sounds like a nerd, but....) is doing a series on WWII bombers hunting subs.
ReplyDeleteI listened to one of his vids -which may be hidden- that had training vinyl (records) of what things sounded like from sonabouys.
This one lets you know what an airborne depth charge sounds like anyway.
