The clip Gene Kranz from Apollo 13 (1995) with Ed Harris
So you're telling me you can only give our guys 45 hours?
That brings them to about there.
Gentlemen, that's not acceptable.
Gene, Gene, we've got to talk about power.
Whoa, whoa, guys! Power is everything!
Power is everything.
What do you mean?
Without it, they don't talk to us, they don't correct their trajectory,
they don't turn the heat shield around.
We gotta turn everything off, now. They're not gonna make it to reentry.
What do you mean, "everything"?
With everything on, the LEM draws 60 amps.
At that rate, in 16 hours the batteries are dead, not 45.
And so is the crew. We gotta get them down to 12 amps.
You can't run a vacuum cleaner on 12 amps, John.
We gotta turn off... We have to turn off the radars, cabin heater,
instrument displays, the guidance computer, the whole smash.
Whoa! Guidance computer. What if they need to do another burn?
They won't even know which way they're pointed.
The more time we talk, the more juice they waste.
That's the deal?
That's the deal.
Okay, John. The minute we finish the burn, we'll power down the LEM.
Now in the meantime, we're gonna have a frozen command module up there.
We're gonna have to power it up using nothing but the reentry batteries.
That's never been tried.
We've never even simulated it before.
Well, we're gonna have to figure it out.
I want people in our simulators working reentry scenarios.
I want you to find every engineer who designed every switch, every circuit,
and every light bulb that's up there.
Then talk to the guy in the assembly line who actually built the thing.
Find out how to squeeze every amp out of both of these goddamn machines.
I want this mark all the way back to Earth with time to spare.
We never lost an American in space.
We're sure as hell not gonna lose one on my watch.
Failure is not an option.
