What's goin' on, Gord H?
I haven't been on here too much myself.
I ain't been to an airshow since I don't know how long (last time was at the Sun N' Fun flyin in Lakeland, Florida, I believe in 2002). Yes, if she thinks regular airplanes are loud (don't know if 'regular' means piston-single, commercial airline jets, or what), she had another thing coming when an F-18 or another fighter jet comes flying over low, and at full throttle.
It's amazing how fast they are, they don't look all that big in the sky due to the speed, but on the ground, their almost at least half as big as a commercial jetliner.
