I was working in a downtown Edmonton office a few years back, when I heard the roar of several Pratt & Whitney's nearby. Lo and behold, I see a B-17G go flying past my window (giving them a good shake, BTW), as it was giving out rides for charity. I was on the 8th floor! It was a CAF plane up for a local airshow.
I can't wait for the water bomber company to begin warming up for forest fire season: they use several B-26's (former A-26A's) - nice sound, and they tend to practice low over our town!
