What is this airplane?
The letters on top of the tail fin is called a registration or tail number, like a license plate if you will.

In this case searching the Canadian Civil Aircraft Register (historical search) for C-FCGV reveals that it is a Beech model 65-B80 with serial number LD 408 and the owner was "Govt Canada Dept Of Transport".


  Introduced in 1966 the B80 was to be the final production model. The B80 was by far the longest produced Queen Air with production lasting some 12 years. Its major improvement was the increased gross weight to a 8,800 lb (4,000 kg). This gave the B80 a useful load of well over 3,000 lb (1,400 kg). Production ended in 1978.


It was removed from the register on 1988-02-03.
