Since this is only tangentially related to photography I thought I'd add it in the Coffee Corner... Having spent a couple of thousand hours inside a De Havilland Twin Otter, I'm rather partial to them. There's a company out of Alberta called Ken Borek Air that has a fleet of about 35 of them, as well as some DC-3's. On their website they have a gallery that shows their planes as well as some scenery shots of the different places they fly. You can see it here:http://www.borekair.com/index.php?cat=gallery
P.S. If you want to see a video clip of why the call the otter a STOL aircraft (short take off and landing), PM me with an e-address and I'll send you one of a plane landing on a muddy flat up north in a distance about the length of the plane itself. It's about 4MB so be warned if you're on dialup...
