Boo!

Terrorists may seek to down aircraft by shining powerful lasers into cockpits to blind pilots during landing approaches, U.S. officials warned in a bulletin distributed nationwide.

The memo, sent by the FBI and the Homeland Security Department, says there is evidence that terrorists have explored using lasers as weapons.

There is no specific intelligence indicating al Qaeda or other groups might use lasers in the United States, they added.

Six commercial airliners in the past four days have had their cockpits illuminated by laser beams while attempting to land, a government official told CNN Wednesday.

"In certain circumstances, if laser weapons adversely affect the eyesight of both pilot and co-pilot during a non-instrument approach, there is a risk of airliner crash," the bulletin said.

The Doc Holiday of laser shooters with his fast draw and deadly aim, a laser pistol in each hand, targets pilot and co-pilot simultaneously to bring down a high-flying jet.

Uh-huh.

In September, a Delta Air Lines pilot reported damage to his retina from a laser beam during a landing in Salt Lake City, Utah.

A report for the FAA in June 2004 examined the effect of laser beams on pilots. Of 34 pilots who were exposed to lasers during simulated flights, 67 percent experienced adverse visual effects at even the lowest level of laser exposure. Two high exposure levels resulted in significantly greater performance difficulties and nine aborted landings.

Then, it could be that the incidents are another military secret experiment, which will ultimately lead to nothing, but which does carry the small risk of damaging the eyesight of innocent pilots.

...but hey, do what you want...you will anyway.
