1, 4, 6, 7, 10 and combinations thereof? Other malfunctions and misinterpretations?

1) it was seen by thermal imagine on the jet and radar on Aegis Cruiser

4) The speed of movement is inconsistent with balloon

6,7) is possible but would require some fundamental physics breakthrough kept in secret

10) There were multiple jet pilots at the scene including top gun instructor. Their account is confirmed by video and radar from the ship.

It's suns and shadows on sea surface. IIRC some of videos show target ranging, which is around the altitude the aircraft were flying, in miles. Aircraft altimeters are almost always in feet so pilots generally don't immediately notice that.

[qaq]

you realise the thing was tracked by AEGIS Cruiser radar and observed from multiple jet fighters at various altitudes visually and using IR sensors.

[RandomLensman]

Parallax effect? Echos? Misinterpreted sensor readings... endless list of possibilities and combinations. Have a lot of sensors, see a lot of odd things - nothing new.

It was seen visually, with IR, and via RADAR, each from multiple observers.

[RandomLensman]

So what? Something caused that observation, but it wasn't something extraterrestrial. You also have to allow for one of the sensors to be wrong/noisy etc. and then being interpreted through the lens of observation via another.

[qaq]

None claiming it is extraterrestrial but there is no evidence to the contrary either. You have too many diverse independent sensors that lined up.

[RandomLensman]

Doesn't work that way: there is always an infinite list of possibilities without evidence to the contrary if you allow for a wide enough "solution space" (even if you have already an explanation).

I dunno. The GIMBAL one looks a lot like 2.
