"A remarkable air traffic control recording from late last month features the moment when a puzzled pilot reports that a thirty-foot-tall triangular object just flew past his aircraft."

I wonder whether he's found the photo?

If the distance and height aren't positively known could it have been something of this sort? "Flat on top...". The payload can be any shape.
