The Aircraft Movement Card for Avro Manchester L7309 shows that, after a spell at Cat AC from 14/11/41, it moved to ‘RAAA’ on 29/12/41, both entries being notified by the Civilian Repair Organisation. Subsequently, on 31/12/41, it was issued to 207 Sqdn.

Can anyone explain RAAA for me, please? In his book on the Manchester, Dr Robert Kirby just prints the initials, offering no explanation, and it isn’t included in Air-Britain’s RAF Support and Training Units.
