My father flew KC-135s for much of his flying career with the USAF and pulled many alerts in his time, ready to be a TOAD should the order come. (That's Take Off And Die, offload every drop of fuel you have to a B-52 if that's what has to be done, and take his chances on a dead stick landing or jump out and trust the parachute.)
Later he moved to RC-135s, which meant no alert requirements as the job was electronic reconnaisance rather than dumping ordnance.
SAC was the epitome of the "tight ship", and I would go so far as to say that it was quite possibly the single most highly militaristic,
hard-assed, no nonsense, mission-oriented organization that has ever been. When your only job is to deliver canned sunshine, anywhere in the world, RIGHT NOW, on target and on time, and you have one chance to succeed as your base will probably be gone before you get back to it, there's no room for slackers.
From the moment the alert sounds, in a REAL war situation, some bases had 15 minutes to live. Any plane that isn't off and heading out to hand out the retribution by the time the first nuke hits the base is the ultimate loser. SAC bases trained very hard to ensure that they'd be able to get every last loaded bird off the ground before the strike hits, and this meant that slackers ended up in a different part of the USAF.
The Russians feared and respected ALL of our armed services, but they were TERRIFIED of SAC. And well they should have been. There was
never a division of any armed service that could and would hit harder or faster.
Despite our technological advances since SAC disappeared, I don't think we have any command that is the equal of it for the same mission.
