“It was actually a C5 Galaxy”
Your Right.I remember seeing the video of the drop and launch of the Minuteman during a commanders call in 1978/79.
That was a hell of an idea to improve on the Nuclear Triad at the time but it would have needed a lot of heavy transports.
Reminds me of that great exchange from “Hunt for Red October”
“Could you...launch an ICBM horizontally?”
“Sure. Why would you want to?”
And I recall seeing this 747-as-ALCM-platform concept in a copy of “The US War Machine” from 1977.
