Yeah if you are shooting from the cockpit it hardly makes sense buying a DSLR and a bunch of lenses. You'll get more usable shots with a nice P&S like a Canon G1X, Nikon P7700, that sort of thing. When I bought my Canon DSLR and lenses, I had no intention of using them in an airplane. It's a difficult environment. That's not to say there are not some great things to take pictures of, just that trying for great images through windows in a cramped, moving airplane is not a recipe for technical quality.
