I've resisted saying this on a public forum for some time for fear of giving someone ideas, but now, with so many recent instances of laser attacks, I think it's just a matter of time before you-know-who's boys mount co-ordinated attacks in many different cities worldwide on civil aviation targets. Unless airlines and authorities prepare for such an attack, it has the potential to have a devastating effect.
The authorities have to make it very clear to anyone who thinks pointing a laser at an aeroplane is a clever idea that any such attack (and 'attack' is the correct word) will be treated very, very seriously - as in attempted murder, for murder is what it will amount to eventually when either professional terrorists or some stupid fool gets 'lucky' and dazzles a pilot at a critical point on the approach or during the takeoff roll.
