We live on Sunderland Road and get City bound planes scooting overhead all the time. I hardly notice them at all as they are small planes with small engines - quite alot of them have propellers rather than jets. The big boys going in to Heathrow make alot more noise it seems to me. Unless I'm mistaken they seem to stack over Bromley and then come in just a bit north of FH, and they can make a right racket. Although not nearly as bad as when I lived in Wandsworth - regularly got woken up at 4.30am by the early morning flights there, and thats never a problem here.
