tailslide93: Recovery from unusual attitudes was/is part of the instrument rating test, or practice for a test.
The IRE (instrument rating examiner) conducting the test/practice would place the aircraft in an unusual attitude then hand control to the other pilot to see if he could make a correct assessment of the attitude, and effect the right recovery action.
The attitude that the aircraft was placed in would depend on the type of aircraft involved.
Nothing unusual about the practice, every RAF pilot who has ever held an instrument rating would have done it for initial issue and on every renewal.
