Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what reports he has received of a sonic boom over the outer-Hebrides on 29 October 2014; and what assessment he has made of the likely cause.
The Department has received no reports of a sonic boom over the Outer-Hebrides on the 29 October 2014. Two RAF Typhoon aircraft were present in the Hebrides area at the time, one went supersonic for operational reasons, but it is not possible to confirm if a sonic boom resulted. Aircraft do not automatically create an audible sonic boom when flying supersonic as it depends on a variety of atmospheric and ground conditions.
