DENVER -
ARTICLE SNIPPET: "However, airport officials say there was no evidence of flying debris that could have caused the cracks."
ARTICLE SNIPPET: "DIA spokesman Steve Snyder says engineers found no electrical problems, and one airline that reported cracks never hooked up to the power grid."
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."
Well that's interesting, thanks for posting Cindy.
