An objection letter from William Curtis, Managing Director of London Heliport, also known as Battersea Heliport, said: “Such a development proposal, so close to an operational heliport in the middle of a capital city, presents unique, immediate, and obvious considerations in relation to a host of technical and other issues, including but not limited to air safety and foreign object debris risk which, in the interests of flight safety and the safety of those on the ground or in buildings around the heliport, must be carefully assessed before the planning authority can determine the application.
