I was SAC, and that statement is laughable.
I was USN SSBN missile systems and have talked with many SAC (Minuteman) launch crews over the years, and it's the dead simple truth. Your systems are much simpler than ours (even without figuring that we had sixteen tubes that we operated individually while you mostly just watched lights) and you didn't (couldn't) operate them or intervene in their operations to the level we did.
The examples of the complexities that you didn't have to deal with are legion (off the top of my head and in no particular order):
- You had no pressurization system. (And even if you did you didn't have to wait for the ship to come to launch depth.)
- Your optical alignment system was set by the loading crew rather than operating in sequence as ours did.
- You had no navigation system interface to deal with as your tubes were fixed in position. (And equally, you didn't have to coordinate your countdown with the ship coming to launch speed or wait for the ship to commence hovering.)
- You did not test the missiles in sequence the way we did. (And unlike us, you couldn't do anything about faults even if you did, the weapons were miles away and maintained by a different crew).
So yeah, the jobs of the prairie dogs waiting in their holes (which is the subject of this discussion) were (are) pretty dammed simple. You punch buttons and swap drawers. If a tube goes down, and it's not at your end, you're screwed because there's f all you can do about it except to wait for a repair crew to be dispatched. (The liquid fuel guys? Yeah, I'll agree they were the real deal. But they're long gone.)
