Hi Chukkablade
Thank you for you your clarification. I had already looked at this document but didn't know what was meant by normal aviation practice.
As for distances I have detailed photographic evidence of it's position on the ground. As for when it overflew, which was a suprise, we have only eyewitness accounts. As for heights though, it is very easy to estimate them when the aircraft in flight is sufficiently close to the building and to the power poles to be able to compare the dimensions directly. No experience is necessary.
I tried to approach the hotel owner as I didn't have access to the pilot. He told me not to disturb his serving of dinners over such a trivial matter. Win friends and influence people.
I'm sorry if I have upset anyone here. I wasn't intending to 'pursue' this matter here. I only came for expert advice. I have not disclosed any details which would identify anyone and would not.
