Easy fix - Compensate anyone living who bought or rented a house before the airport was built by a seven figure sum, tell every person who bought a house at deflated prices due to it being under the flight path to go pound wet sand up their arse and make it a 24 hour airport.
There will be none living who beat the airport in, and if there are any left they will be of venerable age and probably deaf.
The whingers have all had their houses double glazed for nothing.
For them, there is a bus leaving in 5 minutes - be under it.
Best all
