When the operators got continually blasted with the light, they turned the camera on its source and found three men in a culdesac, one of whom was pointing what appeared to be a gun with a laser sight at the aircraft. Officers immediately came to arrest the suspect, at which point he tossed his gun a pellet gun and tried to run before detained.
The footage his unsuccessful escape and prompt arrest is some fantastic justice porn. At some point hopefully society will say lasing aircraft is equally stupid, and hopefully we will come down on that. The penalties are certainly angling to do just that. Catching a drone with a large aircraft can help the military reuse these flying robots—and perhaps even someday deploy swarms of them.
Aircraft like the OBSS, which will have no pilot onboard, are intended to act as teammates for fighter jets like the F The goal is to keep in the air for a year. Sign up to receive Popular Science's emails and get the highlights. At distances of up to feet, it can engulf a cockpit. It remains a distraction hazard all the way up to 12, feet. Smith was using a consumer-grade pointer; the FBI looks unkindly towards anyone using a commercial model.
That same year, Sergio Rodriguez was arrested for the same crime, using a device 13 times more potent than the norm. He got 14 years. What motivates people to do this is somewhat of a mystery. Some people have been arrested because they thought the beam could not reach an aircraft -- but it definitely can! From the air, the beam can look like this:.
Even a very weak beam can be a distraction. The photo below shows a 1 milliwatt beam seen at a distance of 20 kilometers 12 miles across Tokyo. Obviously, seeing laser beams and flashes is distracting to pilots. This is one reason you should never aim at or near an aircraft. This makes it easy for a police helicopter to direct ground officers for an arrest, as described later on this page.
Distracting or flashblinding pilots is dangerous Another problem is that the beam is much larger at long distances than you might think. Even though the laser projects a small, millimeter-sized dot close up, at longer distances the beam can be many inches across.
When the beam hits the windscreen of a cockpit, or the bubble of a helicopter, imperfections in and on the glass spread the light out even more:. The light often is spread so much that the pilot cannot avoid it:.
At higher power levels, it can also cause temporary flashblindness and afterimages like when you look at a bright camera flash, and cannot see for a many seconds afterwards. Glare -- the pilot cannot see past the light as long as the laser is on the cockpit windscreen.
