How to identify what flew over, after the event?
Out in the garden this morning hanging out washing (oh, what an exciting life I lead!), a propeller-driven aircraft went over at high altitude (20,000ft+ at a guess), producing an extremely loud, low frequency noise.
Three questions:
Are there still any propeller aircraft that are this noisy all the time in the cruise, or would it just the particular settings it had at the time?
Secondly, is it possible to determine from the internet what the aircraft was after the event? Purely out of curiosity, I should add, as I have no desire to complain to anyone about it. I looked at Flightradar24 half an hour later but that seemed to be real-time only.
Thirdly, if it was that noisy four miles or so below it, what would it be like in the cabin?
If you know how to search such websites, it passed over Farnham, Surrey, at approximately 10:40BST, heading South.
