The Russian civil aviation has a new enemy - the Russian citizens with common laser pointer. The popular device can be a dangerous weapon when used by criminals. A directed laser beam blinds pilot for a certain time.
On 7 June, when Airbus was 320 with 160 aboard landed at the airport of Rostov-on-Don, the pilot suddenly stabbing pain in his eyes. The crew was professional enough to take the situation under control to time. The plane landed safely.
The investigators of the Interior Ministry of the Rostov region originally assumed that the aircraft can be used under the attack of strong laser beams during festivals, dances and music shows come. The "Dance Party" version was soon rejected it: there is no fun events in town that day.
There was another version available during the investigation - someone used a laser pointer to dazzle the pilot of the aircraft. Unlike laser systems, laser pointers are widely available. The Federal Air Transport Agency said that it had reported a series of such incidents. Some of them occurred in the early summer of 2011.

Another pilot of a German airline says the red laser attack near the airport Domodedovo. All these incidents occurred during a week in the airspace of Moscow.
What makes a pilot feel if someone has a laser in his eyes? If it happens, a pilot is not in a position the equipment on board, which is extremely important to control during the landing.
"On landing must pilot to the data of the aircraft movement, which is a lot of information to scan. You need to also monitor the area outside the cockpit, to control the positioning of the aircraft on the runway. Landing a 800-ton aircraft, especially when it is flying over the city - this is a very complicated and responsible to do something, "the pilot of the aircraft under attack, said Dmitry Leontiev.
As for the investigation of the incident in Rostov-on-Don, eyewitnesses said that they have a young man standing on the balcony and showed an intense laser beam in the sky looked.
Mikhail Solovyov, the director of a company produces laser devices, said that laser pointers are usually very powerful units, because people use them at conferences and seminars. Such information may in fact hurt our eyes, said Solovyov.
A laser pointer is in any internet shop for as much as $ 20. The laser device is strong enough to light (100 milliwatts) in a match. More powerful units (300-500 milliwatts) can be overcome distance of ten kilometers. When used on a near object, it can melt plastic and even thin metal.
Green laser pointers are prohibited in the United States. Green is the brightest color to the human eye. There are no such restrictions in Russia, though.
Professor Eugene Latush believe that was the pilot of the aircraft, the landing at the airport in Rostov, were attacked by a 200-milliwatt-pointer. Such pointer with the laser on the crystal with neodymium.
Laser attacks were also reported in Germany is Hamburg. The City Police arrested two teenagers who showed their laser pointers at airplanes, just to have fun.
A laser beam pointed in the eye may result in a spasm of blood vessels in the organ of vision. A pilot may be 10 minutes in such a blind attack. Unpleasant symptoms may disappear in half an hour, but the landing usually takes several minutes.
