Recently I watched a show on UAPs and some references to the recent Pentagon report. It was on the SCI channel. Someone claimed to clock a UAP (on a navy ship) with radar that descended from 28,000 feet to sea level in less than one second. I do not know if the claim is factual. That UAP would drop at nearly escape velocity of earth, measured in km/s and then shoot off in another direction. The time provided in this descent calculated to some 36,000 fps rate so very close or faster than 11 km/s. This is the only *hard* metric I have encountered so far for speeds of UAPs - clearly reported. The presentation I watched could be all wrong here too. Here is what I observed recently while viewing the Moon close to Last Quarter phase. This was the morning of 28-Oct-2021.
[Observed 0900-1000 EDT/1300 UT - 1400 UT. Last Quarter Moon 28-Oct-2021 2005 UT/1605 EDT. Enjoyable morning views of the Last Quarter Moon at 31x. Crater details along terminator line like Eratosthenes, Archimedes, Plato, and in the south limb, Moretus crater distinct. Near 0953 EDT/1353 UT, a high-altitude jet leaving a contrail flew across the FOV traveling south, straight across the Moon. Quite a view of the jet and Moon
This confirms that the Moon is farther away from Earth than jets fly above the Earth
Virtual Moon Atlas reports the angular size of the Moon 30.46 arcminutes. At 31x, the telescope FOV ~ 1.6 arcminutes. The telescope view resolved ~ 9.6 arcsecond on the lunar surface or about 18 km diameter. 1 arcsecond resolution about 1.9 km diameter given the Moon's distance near 392250 km. There were cirrus clouds this morning with light winds from NE at 3 knots and temperature near 13/14C. Easy morning viewing.]
When it comes to these UAPs buzzing *all around*, I would think many amateur telescope users would be reporting an abundance of sightings given the popular reporting while they observe from many different locations all over the earth
