Just watched a clip on BBC News website of a Chinook delivering supplies to the Foss bridge. The clip was taken from a platform initially above and slightly behind the Chinook and later from above the stbd side. There is no indication of whether the footage was taken from another helicopter or a drone. If it was a drone, surely this posed a potential risk to the Chinook as it was outside the pilots view. Any thoughts?
