If planes, with active propellers or jet engines, are only audible for a diameter of 20-50km around the vehicle, how could a falling unpowered ring of metal be audible from 200km away as per TFA?
- jcims 2y agoIt would have been supersonic at a very high altitude and likely came in at a steep angle, so sonic boom + large exposure area + long path.

- zardo 2y agoWhile it was supersonic it would have produced a sonic boom all along it's path of travel.
