Laser Warning System
In May of 2005 NORAD started using a laser warning system to warn pilots that cross into restricted airspace. The bright laser beams, which flash red-red-green, are easily seen, even during daylight. The laser beams can be seen 15 to 20 miles away. Other pilots are unlikely to see the lasers because when activated the directional beams are pointed at the aircraft that has crossed into restricted airspace. Multiple lasers could be activated.

Famous quotes containing the words warning and/or system:
“By day thy warning ringing bell to sound its notes,
By night thy silent signal lamps to swing.”
—Walt Whitman (1819–1892)
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)
