Dear Sir,

Recently drones stopped Aircraft landing at Gatwick Airport. My concern is that terrorists may be deliberately trying to cause Aircraft to crash, either on take off , or landing. A device to stop drones has been invented , to stop drones being used to deliver drugs/phones etc. into Prisons. Could this signal blocking device, be adapted to stop drone flying at Airports? Trials will be needed to ensure that the airport equipments are not affected, only the drones.
Yours faithfully

F. S. Jessop
