Thanks for your comments but no progress.
The flight path was not absolutely standard at all hence my posting. If that is being posted as accurate around the the Ockham hold then so much for technology and the Nigels . The aircraft was certainly a few miles north of what I believe is normal and judging by the noise was lower than any commercial airliner has been near my house.
I have lived in my present house for 40 years, prior to that worked for a major airline for 35 years and am quite aware of aircraft and paths around here.
I have never been aware of the sound or sight of aircraft in the Ockham stack. The aircraft was exceptionally loud.
By "folks" you mean you and four others?
It means that others were also concerned at the the totally non standard event.
