From the Earth to the Moon1998

Clinton Anderson:
[at the senate inquiry following the Apollo 1 fire] Colonel, what caused the fire? I'm not talking about wires and oxygen. It seems that some people think that NASA pressured North American to meet unrealistic and arbitrary deadlines and that in turn North American allowed safety to be compromised.

Frank Borman:
I won't deny there's been pressure to meet deadlines, but safety has never been intentionally compromised.

Clinton Anderson:
Then what caused the fire?

Frank Borman:
A failure of imagination. We've always known there was the possibility of fire in a spacecraft. But the fear was that it would happen in space, when you're 180 miles from terra firma and the nearest fire station. That was the worry. No one ever imagined it could happen on the ground. If anyone had thought of it, the test would've been classified as hazardous. But it wasn't. We just didn't think of it. Now who's fault is that? Well, it's North American's fault. It's NASA's fault. It's the fault of every person who ever worked on Apollo. It's my fault. I didn't think the test was hazardous. No one did. I wish to God we had.
