Many thanks for all the replies -I did look at the LHR web site but it wasn't very forthcoming and there was a difference in dates between what I saw and what ,as Gonzo explained, actually happened.
I certainly notice the late evening heavies to Africa or S America where they use SAMPTON departures but often pass close to Camberley.
Is Midhurst really no more, I have always thought there was big variation in tracks for aircraft using Midhurst departures an not just caused by aircraft type, some pass over lightwater /chobham and some over Camberley where they sort of fly through the turn having already got themselves west of Midhurst.
AND finally is Ockham hold really moving anytime soon.
Tks again
