The real story behind all those UFOs the Air Force was shooting down last week is quite embarrassing.
I’m guessing someone at NORAD has now figured out why the sensitivity settings on the radar was turned down in the first place.
@boelder @carnage4life Airliners are already certified to withstand impact from birds. The present regulations, that specify maximum weights and areal densities for unlicensed balloons, must be derived from those about birds.
