"History In The Telling"

Rating: Null/10 (24 January 2004)

Another user here at IMDB asked what a Main Bus-B Undervolt was. In the Apollo CSM's, whenever there was a substantial loss of power in one of the fuel cells, it would register on the panel as an undervolt. On Apollo 13, they lost two fuel cells. As a matter of fact, they lost four major systems--an unheard of disaster, and an outcome which could have rivaled the tragedy of Apollo One, were it not for the massive rescue efforts that were launched on Earth.
Yet they did make it back. And this docudrama by Ron Howard is one of the all time, great space epics.
