Terrorists may seek to down aircraft by shining powerful lasers into cockpits to blind pilots during landing approaches, federal officials are warning in a bulletin distributed nationwide.
The memo sent by the FBI and the Homeland Security Department (search) says there is evidence that terrorists have explored using lasers as weapons, though there is no specific intelligence indicating Al Qaeda (search) or other groups might use lasers in the United States.
"Although lasers are not proven methods of attack like improvised explosive devices and hijackings, terrorist groups overseas have expressed interest in using these devices against human sight," the memo said.
"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 agencies said.
In September a pilot for Delta Air Lines reported an eye injury from a laser beam shone into the cockpit during a landing approach in Salt Lake City. The incident occurred about 5 miles from the airport. The plane landed safely.
There should be some kind of technological solution to this problem. I just hope people don't have to die this time before someone implements it.
