I'd have loved to see the B-17. I live under one of the approaches to CYOO (Oshawa Municipal) and there is a cargo transport company there using a DC-3, so I'm lucky to see that often. There have been other cool craft as well, common but still cool, like Learjets, Citations, the Government of Canada's Challenger....but the best of all so far was an RCAF SAR Griffon (Huey if you're not Canadian) cruising over low enough in altitude to see the winch operator's face. That chopper made windows rattle here. As well, one of the lieutenants from CFB Trenton (CYTR) did his original flight training at CYOO, and once in a blue moon he makes a fly by with a touch and go in a Globemaster.
For me, all that is exciting, however some of my neighbours complain about the noise. Fortunately, I find them hard to hear over the various planes' engines
