I am sure that there is a reasonable explanation for both of these sightings, but here you go: similar UFO seen over Miami and Los Angeles on different days.

Now, when I say UFO, I only mean "unidentified flying object".  I am not asserting or assuming anything, it's just that I don't know what this thing(s) are.

It appears to mimic a re-entry vehicle hitting the atmosphere at an angle instead of straight-on, allowing for a longer "burn".

[CAUTION:  FOUL LANGUAGE IN VIDEOS]

Tell me what you think.  The first video is reportedly from the Miami area, uploaded to Facebook September 2, 2015.

 

The next video was reportedly taken in the Los Angeles area and uploaded to Facebook on November 7, 2015.

Could they be a video of the same object, and just reported (erroneously) from different areas of the country?
