An aspiring, heartless NASA drone will have already noted that absorbing the life insurance costs for those lost/left behind will be far cheaper than going all out by attempting extreme rescue measures, using the word “expensive.”
We didn’t see NASA sending out rescue teams to attempt to aid any possible Challenger survivors on January 28, 1986, though, as was later determined, those crew members—possibly all of them—likely survived the crash and died only many hours later.
I don't know where that came from, but it's malarkey. The Challenger crew may have survived, and even remained conscious, during the midair dissassembly of their spacecraft, but if so, they certainly died instantly during the >200g deceleration they encountered when the crew cabin hit the water 45 seconds or so later.
