asked the Secretary of State for Air what proportion of the aircraft representing bombers in Exercise Emperor were of types in service in 1945.

Rather less than one-third.

asked the Secretary of State for Air what was the average height at which high-flying bombers approached their targets in Exercise Emperor.

It would not be in the public interest to give this information.

asked the Secretary of State for Air what lessons have been learnt from Exercise Emperor; and if he will make a statement.

The results of Exercise Emperor during which a number of operational techniques were tried out for the first time by both the attacking and defending forces, are still being analysed and evaluated. I can, however, say that a number of valuable lessons have already been learnt and are being applied. The exercise was well worth while and provided valuable training experience.
