What about this one from Puerto Rico. I'd like to know your views on this one. USA or Alien maybe ?
Without knowing more... just watched the video without audio so far to focus on visuals. But...
At 1:12 a distinguished vapor is seen behind... maybe from a fuel enrichment in its thruster.
At first I thought it was a high speed object vapor trail caused by wing vortex from a change in speed or tight maneuver, but relative speed across highway shows it isn't that fast.
At 1:28 relative size to cars on street and it is small and is not moving that fast... perhaps about what a typical model radio controlled plane would do,
It appears to be circling the area based on the screen data it went from 220 degrees right to 360 and beyond...
This may be a radio controlled 'tiny jet' due to profile at 2:00
Probably a test flight that took off prior to the camera which appears to be expecting its postion to catch it shortly after it established flight, and likely scheduled to circle the camera point.
My conclusion. It is a test using small short range RC plane for simulating some brief recon test or to test the camera equipment that filmed it. The camera may be mounted on a drone as well.
