Under a parallel agreement, the Joint Air Training Scheme, South Africa trained 33,347 aircrew for the South African Air Force and other Allied air forces. This number was exceeded only by Canada, which trained 131,500 personnel. Southern Rhodesia at the time was a British Crown Colony (rather than a Dominion) and was not involved in the negotiation or signing of the BCATP; the Southern Rhodesia Air Force was subsumed by the RAF in 1940. However, Rhodesia provided significant EATS facilities and contributed personnel to British units.
