AIR TRAINING CORPS (ATC)
For three years during World War II a unit of the Air Training Corps (ATC) operated at the School as a separate body to the cadets. The unit was under the direction of a staff member Flight-Lieutenant T Henderson. Senior boys were allowed to join the ATC, and, eventually a large number of them served in the RAAF.
