Could you bother to please isolate and highlight maybe with a circle the bit of the craft still poking out from behind the building in the last frame it did so in . . . and then the peak on the left side of the building where last seeable?
Blessings,
Check out Joe’s enlargement in post #55, Quix.
It’s the lighter-colored rectangular blob just below midway down the left side of the enlargement. It is behind the building, as comparison with the previous frame of the video shows.
