HC Deb 25 June 1952 vol 502 cc2215-6
10. Mr. Emrys Hughes

asked the Minister of Civil Aviation why he has issued the regulations "Purple Airways" for the guidance of airport authorities.

Mr. Lennox-Boyd

"Purple Airways" are instituted temporarily on specific occasions to provide for the safety of Royal flights on their varied routes.

Mr. Hughes

To what extent does this interfere with normal air traffic?

Mr. Lennox-Boyd

To a negligible extent. I am sure that the whole country will willingly do all that is possible to ensure that the Royal Family, on their many public duties, are given the fullest possible protection in the air.
