Re the use of British Airways rather than BOAC.
According to Winston Bray's book Sir John Reith claimed to have originated the full name.
In 1941 the Director-General Leslie Runciman instructed that the Corporation was to be known simply as British Airways.
In 1944 a new management restored the Speedbird and the full name.
I was BOAC and although BEA was a sister corporation the two companies often seemed to be barely on speaking terms.
As a small example when I started staff travel was available on just about any airline in the world-except BEA.
