Indeed it was the 'ole 707, Blue Eagle, circa mid-seventies.
Then, the 707 was the larger fleet, with the 747's close behind.
Ah, the good 'ole days.
Same general style of management, then as now.
Many of the 707 guys joining were recently retired from BA, and retraining on the 707 was a bit of a letdown, according to them anyway.
A regular revolving door with these folks, as nearly all left within two years.
