Laser Beam Struck Papal Jet as it Prepared to Land in Mexico - Alitalia
Feb 17, 2016 Source: McClatchy
Feb. 17--The crew that flew Pope Francis into Mexico City on Friday noticed a laser light shining on the plane as it prepared to land at the start of a five-day trip, Alitalia said in a statement Wednesday.
The jet's captain, Massimiliano Marselli, reported the incident to the control tower, which alerted local authorities, the airline said.
Alitalia called the communications "standard procedure" and said the Airbus A330, which flew out of Havana, Cuba, landed in Mexico City without harm to passengers or crew.
An audio recording from the pilots on board the four-year-old passenger jet reported the laser beam coming from a 12 o'clock position from a distance of 25 miles.

The problem
http://www.laserpointersafety.com/laserglasses/laserglasses/laserglasses-ps.html
Inexpensive laser pointers with up to 0.5 mW of stated power can easily be purchased in corner stores or electronics shops. As Class 3R laser devices, these so-called low-power pointers are available for general sale and use with recommendations to avoid exposure to the beam. The popular green laser pointers are DPSS (diode-pumped solid-state) devices often consisting of a neodymium-doped yttrium aluminum vanadate (Nd:YVO4) laser at 1064 nm, pumped by an 808-nm diode laser and frequency- doubled via a potassium titanyl phosphate (KTP) crystal, halving the wavelength to output the desired 532-nm green light. The power ratio of the 532- to 808-nm and 1064-nm radiation is approximately 1:3 . To prevent the pump light (808 nm) as well as remaining nondoubled 1064-nm light from exiting the devices, they are designed to include a near-IR-blocking filter.
These easily accessible, cheap laser pointers can be used either maliciously or accidentally to illuminate cockpits of airplanes (on takeoff and landing) or helicopters (in urban environments). When a cockpit is illuminated by a green laser pointer, the crew can suffer from any of four potential effects and their associated hazards:
Startle ? Distraction
Glare ? Disruption
Flash-blindness ? Disorientation
Eye damage ? Incapacitation
