The
British Commonwealth Air Training Plan (
BCATP), often referred to as simply "
The Plan", was a massive, joint military
aircrew training program created by the
United Kingdom,
Canada,
Australia and
New Zealand, during the
Second World War. BCATP remains as one of the single largest aviation training programs in history and was responsible for training nearly half the
pilots,
navigators,
bomb aimers,
air gunners,
wireless operators and
flight engineers who served with the
Royal Air Force (RAF),
Royal Navy Fleet Air Arm (FAA),
Royal Australian Air Force (RAAF),
Royal Canadian Air Force (RCAF) and
Royal New Zealand Air Force (RNZAF) during the war.
