Wot? BA hasn't ever had priority at LHR?
There was always the case of the BAC 1-11 (VY?) which always got priority after it was left pointing towards Boscombe Down one day and forgotten while on vectors for 09L/R (in my day)
Surely West Drayton could hear the aforementioned 1-11 converting fuel to noise...and merely hoped it would quieten down a bit as it headed out towards Boscombe
