I mean Corbell can selectively quote all he wants, but the Navy pilot specifically says it looked like a quadcopter.According to this article quoting Corbell on the 2019 incident. An anonmyous crewman said some of the objects were flying for 4+ hours and reached 21k feet.
As we know, hybrid drones can fly for that long, one example was the previously mentioned skyfront drone that flew for 13+ hours
The other aspect is altitude. This reminded me of a thedrive article which noted a 2018 incident in a warning area. 4 objects were tracked flying at 16k - 22k feet. When a pilot investigated one of them he saw a quadcopter drone flying at 20k feet. See below

GIANT KILLER is a military Air Traffic Control (ATC) call sign used within certain regions of the contiguous United States (CONUS). The callsign is primarily administered by the United States Navy for military flight operations on the East Coast.[1]
where does he get "apparently impervious to anti-drone Navy technology" from?Corbell can selectively quote all he wants
4 foot at 2000 feet is an apparent size of 0.114592 degreeswhere does he get "apparently impervious to anti-drone Navy technology" from?
I believe identifying a 3-4 ft wide quadcopter at 2000' requires some kind of optics, to the naked eye it'd look like a speck in the sky.
thank you for the correction, I mistyped and computed 4/20000=0.0002 rad as the angular size instead of 0.002 rad. The correct value makes the quadcopter ~7 "eye pixels" wide, which is probably enough to get some idea of what it is, especially when in motion. It corresponds to 1/16" seen from 2.5', or 2mm seen from 1m distance.4 foot at 2000 feet is an apparent size of 0.114592 degrees

- Angular resolution: about 1 arcminute, approximately 0.017° or 0.0003 radians,[1] which corresponds to 0.3 m at a 1 km distance.
There are also two other hypotheses that I'd put higher on the list than 4+ hour drones.According to this article quoting Corbell on the 2019 incident. An anonmyous crewman said some of the objects were flying for 4+ hours and reached 21k feet.
