I live really close to the airport in Nashville, and the school I taught at was just a few minutes from my house. One of the teachers on my team, Mr O, owns his own Cessna...so he naturally knows the flight paths in town.
We knew the President was coming into town that day (this was when George W Bush was in office) but since that was a fairly regular occurrence didn't really think much of it. Until Mr O came to my room during our planning time first period and told me a bit of insider intell. Apparently, the runway normally used for Air Force One was being repaired, so they would have to come in on the flight path directly above our football field!
So long story short, we let the kids watch the President come into town. I got a few pictures, although my camera at the time didn't quite have the zoom that I'm now used to!
