This film depicts attempts to return the crewmen of the Apollo 13 mission safely to earth following an explosion onboard the service module. The film emphasises the Mission Control and spacecraft teamwork that overcame the life-or-death problems of Apollo 13, as well as the worldwide reaction to the crisis. Listen out for the famous quotation by Jack Swigert at 4:43 into the video. Warning: this video is 150mb in size.

If you can spare 40 minutes, this excellent and entertaining lecture by David Scott of Apollo 15, given in Houston in March 2014, is well worth it.
