Then they wonder why windshields crack on planes?

While officials are still puzzling over why the windshields cracked on about a dozen airplanes at DIA on Friday, one theory has been offered.
At least three airlines reported cracked windshields during high winds at Denver International Airport, some in the air, some on the ground.
Airport officials say there was no evidence of flying debris that could have caused the cracks.
But Saturday morning, Frontier Airlines spokesman Joe Hodas says there is a theory that there may have been a power surge while airplanes were connected to auxiliary power lines at the gates.
Hodas says airplane windshields are heated electrically.
A surge could have done something to weaken them.
Hodas says the theory is considered unlikely, but it's the best anyone can figure at this time.
Airport spokesman Steve Snyder says engineers checked the electrical connections and found no problems, and besides, he says, one airline that reported cracks never hooked up to the power grid.
