I did actually see this one as it was transmitted and I wondered if the clip would find it’s way to ATS at the time. The angle of flight and the
geographical location are about right for an aircraft climbing out of Heathrow, allthough I do think it seems to be travelling a tad more swiftly than
I remember from my time living in the area. I am inclined to say regular aircraft, but as always I am open to other interpretations.
