The US army is ‘nonetheless not sure’ what the flying objects it shot out of the skies over North America have been – and the way they have been capable of keep aloft.
President Joe Biden ordered one other object – the fourth in whole this month – to be downed on Sunday.
Because it was touring at 20,000ft (6,100m), it might have interfered with industrial air site visitors, the US mentioned.
A army commander mentioned it may very well be a “gaseous kind of balloon” or “some kind of a propulsion system”. He added he couldn’t rule out that the objects have been extra-terrestrials.
