§ Mr. Llewellynasked the Secretary of State for Air to what extent the erection of the television station on the proposed site at St. Lythan's, Cardiff, will constitute a danger to aircraft using St. Athans Airport; on what date he received official intimation of the proposed change of site; on what date he took a decision concerning the suitability of the St. Lythan's site; and on what date his decision was conveyed to the Postmaster-General.
§ Mr. A. HendersonThe aerial mast for this television station will be 750 feet in height. It will, therefore, constitute a general obstruction to air navigation, and it will accordingly be necessary for the mast to be fitted with red obstruction lights. My Department was first officially consulted about the proposed change of site on 15th November and was able to give the necessary clearance on the same day.
