I have been reading about the increased number of incidents in which pilots of planes report that they have been blinded by laser beams aimed at the cockpit from the ground. I was surprised by this since the lasers one uses in everyday life are quite low in power and it is not easy to aim them. But it turns out that these lasers, which can be easily purchased online, are more powerful than the ones used in meeting presentations and are getting even more powerful. Authorities are treating them as dangerous practices and urging a crackdown.
I still wondered what the chances were that the people using them would be able to accurately hit a plane cockpit even if it was fairly low because it was taking off or landing. But these videos taken from helicopters and planes show that lasers sweeping across the pilots’ field of vision can produce quite a blinding effect and so the concerns about this practice have to be taken seriously. The people doing such things may see them as pranks but they are dangerous.
