UFO Sighting in Wythenshawe, England on 2017-07-08 00:00:00 - Large but far away, silent, moved slow gradual speed off.

I live in a tower block eighth floor so im always looking out and up..This particular evening i was busy tydying up when i spotted an aircraft, just taken off ( live approx 2 miles from international airport) nothing unusual until i spot close behind the aircraft a 'black' orb almost as if following the plane. it only lasted approx 2 minutes as it veered away from the aircraft and towards my block but was very high up. i lost sighting due to it moving directly over my block.At first i thought it may be a balloon but i think it was too far up for that. and it actually changed direction albeit slightly.
