SHJ.. I'm not sure if an outbound from Brize would fly over London. If it was bound for Afghan areas it would probably pass well south of London and out over Dover. How high it would be abeam London is anyone's guess but I'd bet on 20,000ft plus.. We often hear a late night 747 out of Heathrow and if the air is still and windows open we can hear it for ages..
Sorry I can't help. The SBS Forum might.....
