The Biography Channel had a documentary of the Star Trek captains in 2009 called The Captains of the Final Frontier. Basically, it compares the fictional captain characters, unlike William Shatner’s Captains documentary that was more about the characters. Lots of stats given for your Star Trek geeks, too! 
The official description of The Captains of the Final Frontier is below, along with the full documentary video!
Earth from Space is by far the best video I have ever seen about the Earth. The videography is absolutely stunning, but the information presented also rivals that. See how natural forces work on Earth, on its own and, of course, together. You really get a sense of how everything influences everything else. There’s a TON of information to learn, then contemplate consequences after that. Headache medication makers should really sponsor these awesome documentaries!
Below is the entire documentary. You can watch it in HD if you have the bandwidth and want to see it in all its glory. Do that by clicking on the YouTube icon near the bottom left corner.
The Lucky Few is an hour long documentary about the story of the USS Kirk and its crew in their incredible mission to rescue Vietnamese refugees during Operation Frequent Wind in the final days of the Viet Nam War.
As the War was coming to an end on April 29th to 30th, 1975, Operation Frequent Wind airlifted about 7100 “at risk” Vietnamese (to death from the Communist Viet Cong) and American civilians out of Sai Gon, the capital of South Viet Nam. Some lifts were scheduled. Others were not. The relative American small warship USS Kirk, a destroyer escort, and its crew suddenly found themselves in the midst of a flock of unscheduled airlifts, to which it admirably accommodated even though it was neither meant nor ready to do any such thing.
