Over the years there have been many cases of people using lasers to annoy pilots and co-pilots and even try to force a plane to land. We should be wondering why there hasn’t been something done about this, apart from making it a criminal offence.
One solution would be the use of reflective films on cockpit windscreens to stop the laser being able to ‘access’ the cockpit and bother the flying crew. Using double-thickened glass with the reflective screen being inside it, as well as on the side within the cockpit acts as a double safety measure.
A secondary system, I’m not sure if this exists, could be an external light screen that would extend a light field (outside of human sight range) in front of the plane that would change the colours coming from the laser and possibly negate any affect, the light would be ‘bounced’ from the light field either above the plane, or back at the original location of the laser.
I like the idea of having safety systems in place to stop people coming to harm and being able to carry on with their work.
