HC Deb 19 November 1941 vol 376 c284
17. Mr. Purbrick

asked the Secretary of State for Air whether a bomber pilot can use his powers of discretion and return to his base without reaching his objective if he is of the opinion that from the weather or from the state of his machine it would be unduly jeopardising the aeroplane and its crew?

The Secretary of State for Air (Sir Archibald Sinclair)

Yes, Sir.
