I grew up living next door to the owners and operators of SALAIR, the airplane you see flying at the beginning of this video. This is a superb documentary on the history of the most popular propellor airplane in the world, the DC-3. (I had to delete the original and repost this as it was flagged by YouTube with a copyright violation that I was given the option to correct, which I did).
