Apollo 13 - Official NASA Documentary

I remember seeing this many years ago and just came across it on the Internet. It's about 30 minutes long, really amazing.

"NASA produced documentary of the near-fatal Apollo 13 mission in 1972. Includes the on-board explosion and efforts by the ground crew and flight crew to troubleshoot the malfunction and design and implement contingency procedures to bring the crippled spacecraft home."
