As for the first, there are those out there who love airplanes. Some take pictures and treat photographing airplanes the same way they treat photographing nature scenes or wild animals. Perhaps Billy Joe and Bubba were trespassing, or didn't want to hassle with employees and beat feet.
As for trashing the Constitution...
I have no idea why anyone would want to do that, but if you poke around FReeprland, you will find PLENTY that do.
FReep on,
