I wonder if the airport should consider changing the departure route slightly or spread departure routes so that occasionly some departures turn right after take off and not left? I have seen about 12 departures take off over the town centre over the years.
Wouldn't happen unfortunately unless the Dunstable Gliding Site closes down. Those 12 you saw were most likely weather avoiding, VFR or Dunstable was closed and a right turn was coordinated with radar before departure
