Weird comet / spotting.

[DimaSky 0]

I was in Sheffield at ‎19:35:43 on the 06 ‎May ‎2020 when using a bridge camera i spotted a quickly moving object at quite a distance away (50x zoom). It was followed by a grey smoke trail and was leaving the atmosphere at a slight angle. It was spotted looking NNW. The object's trail has no sort of flames. Could it have been a man-made object? Does anybody know what it was or have any information on it?

Looks like a plane to me.

It's just a jet liner.

At that time the Moon was just rising in the ESE. So the plane was travelling approximately SW. Assuming it was in the cruise at 30,000 ft+ it will have been at some distance, maybe 40 or 50 miles. As it comes round the curvature of the Earth it gives the impression of flying at a steep angle and you can see the underside.

Nothing shows as a likely candidate on flightradar24.com but not all commercial, and very few military aircraft carry an ADSB transponder.

Pretty typical plane observation though

Obviously a plane and contrail. Zooming in, there is a large tail assembly and the fuselage looks raised near the front, resembling a Boeing 747.
