In 1993 I was working for Grand Airways based in Las Vegas when the Rio hotel went up.
They put up a laser light show as part of their advertising for the new hotel that turned out to be aimed up the arrival cooridor for McCarren Airport (LAS).
Grand Airways had 2 pilots injured and America West has a few as well. This went on for 3 weeks before they moved it.
This is nothing new unfortunately, just getting more and more common.
