§ Mr. Gerald Howarth
To ask the Secretary of State for Defence what arrangements are in place to ensure the safe operation of United States military unmanned air vehicles while in UK airspace; whether there have been breaches of these arrangements in the past 12 months; and if he will make a statement. 
§ Mr. Ingram
Requests from the US to operate military unmanned air vehicles in UK airspace are handled on a case-by-case basis. To date, there has only been one such request for overflight of UK airspace, which was approved. Stringent procedures are in place to ensure safe operation of such flights. There have been no breaches of these arrangements.
