CDAC02298: Letter to the Canadian Embassy to the US (Mar 5, 1959)

After careful consideration, the Canadian government granted the USAF blanket permission for four months in principle due to the importance of deterrence for foreign policy and shared military aims. The main caveats to this agreement include Canada’s right to revoke permission at any time, regular service-to-service communication about individual flight details, and a particular focus on secrecy about the operation.
