HC Deb 17 April 1929 vol 227 cc240-1
14. Mr. DAY

asked the Secretary of State for Air the number of aeroplanes belonging to the Royal Air Force in which the pilots' cockpit is enclosed in safety glass?

The UNDER-SECRETARY of STATE for AIR (Sir Philip Sassoon)

The pilot's cockpit in Service aircraft is not closed in, but is protected by a windscreen of safety glass. Enclosed cockpits are now, however, under experiment, and in these safety glass is being employed.

Mr. DAY

Can the Under-Secretary say whether they are also experimenting with wind screen wipers?

Sir P. SASSOON

I should like notice of that question.

Lord APSLEY

May I ask whether this glass is being used in air liners?

Sir P. SASSOON

I believe it is being used already.
