SAN ANTONIO -

San Antonio authorities are launching a new campaign to keep people from pointing lasers at airplanes.

The reward for turning someone in could be as much as $10,000.

"Laser strikes effect commercial, military, law enforcement  and private aircraft," said Calvin Shivers, FBI assistant special agent in Charge. "They also pose a serious threat to pilots, passengers and the general public."

Pointing a laser at an aircraft is a felony that could land you in prison for up to five years.

Officials say it's a big problem all over the nation.

Pilots say they encounter laser pointers more than 10 times each day during the most critical phase of their flights -- while they're landing.

Laser pointers can light up the cockpit and, in some cases, can blind pilots, putting the safety of everyone on board and people on the ground at stake.

"You can be flash-blinded or have momentary blindness," said First Officer Wolfgang Koch, with Delta Airlines. "So at some point, you're going to have to rely on either another crew member to fly the aircraft or the automation of the aircraft."

Last year, laser strikes hit an all-time high of 3,900, and it's estimated thousands more go unreported.

San Antonio ranks among the top 15 cities in the nation in air strikes against aircraft.

There were 50 laser strikes reported last year in San Antonio.

"Just two weeks ago, we were investigating a situation where two individuals were lasing an aircraft in the Northeast area of the county," said Bexar County Sheriff Susan Pamerleau. In this incident, two teens were arrested for pointing a laser at a DPS helicopter.

In fact, FBI officials said Tuesday that a majority of these strikes have been committed by teens, many who have been difficult to track down.

"Part of the reason why we have difficulty in prosecuting these cases is it's really  difficult to collect the evidence and to have eyewitnesses on the scene who can identity the perpetrators," said Michelle Lee, with the San Antonio FBI office.
