§ Sir F. SYKES asked the Under-Secretary of State for Air whether a series of 1517W night-flying tests has been carried out on the Cairo-Baghdad air route or in other tropical or semi-tropical areas; if so, whether regular night flying under such climatic and atmospheric conditions is considered to be practicable; if the conclusions derived from such tests have been communicated to the Dominion and Indian Governments; and, if such tests have not been carried out, whether, in view of the great importance of night flying, they will be put in hand at the earliest possible date?
§ Mr. LEACHThere is no present intention of operating the Cairo-Baghdad air route by night, but night flying is carried out as a regular part of the training of the air squadrons in the Middle East generally and in India. Any data derived from the experience of the squadrons in those areas are at the disposal of the Dominion Governments.
