When I take a break from cars (and it doesn't happen very often), one of my favorite hobbies is following, researching, and learning about old propliners. From DC-3s to Lockheed Contellations, I've always been fascinated since I was a kid with old propliners. I've even had a chance ot fly in a DC-3, which was an awesome experience.
One of the websites I go to all the time, www.conniesurvivors.com , had a link to a really cool clip of a Constellation starting up. Just wanted to share it with everyone, because it's really cool.
