HC Deb 13 March 1939 vol 345 c48W
Lieut.-Commander Fletcher

asked the Secretary of State for Air on what date the Air Ministry received a request for an officially recognised air-route over the Southampton area; and on what date the Southampton controlled zone was enlarged?

Captain Balfour

Requests for the establishment of an officially recognised air traffic route in the Southampton area were first made early in 1937. It was not practicable to comply with the request in the precise form in which it was made but other means were devised to avoid the risk of collision. The Southampton controlled zone was enlarged as from 29th June, 1938.
