The Clayton Knight Committee (CKC) was founded when Hitler was enforcing the expansionist policy on Europe. Britain, along with her Commonwealth countries recognized that in order to halt him, they had to establish a dominant air force. Canada, Australia, Britain, and New Zealand created the British Commonwealth Air Training Plan (BCATP). It also went by the 'Empire Air Training Scheme'." Each country had responsibility for varying aspects of the overall plan, such as aircraft engines (Britain), trainers (Britain), cost of elementary trainers (Canada), etc. It had plans to prepare and instruct 150,000 potential airmen.
