Regarding the plane windshields...
This may sound odd, but could a high-pitched tone directed right at the planes or a certain vibration from a plane going overhead -- could either of these possibilities be accurate? Or could it be temperature-related?
If all else fails, blame Bush -- that's using the "easy button."

"Chad may face genocide, UN warns"
That doesn't sound odd if you're a Tom Clancy fan. Everytime I hear about a laser being aimed at airplanes, I think of Tom Clancy. (also passenger jets crashing into buildings) Anything seems possible now days.
