Heard this from a friend...

Date - 1980.  Person is driving a '79 Monte Carlo through town.  All
of a sudden the windshield cracks.  It was not caused by a kid
throwing rocks because the crack was rather straight.  Anyway the
person pulls off the road and a cop pulls up a few seconds later.  The
cop had been using radar and the windshield had a built in antenna
wire.

Could radar hitting the wires in the glass cause them to resonate so
much that the glass cracked?
