This is exactly what I thought when I started reading this topic yesterday.
While 11 11's thesis could be possible, I find it unlikely, given the circumstances. Someone mentioned the laser has a huge range - given that these
types of lasers have a rapid falloff in power over distance, it's not unwise to assume it could heat something up at close range.. Whether it could
heat something up enough to make any difference to a plane colliding with a building in such a short space of time, without any other noticable side
effects however is unlikely IMO.
I had never thought of this until 11 11 brought this topic up. And I have seen the flashes on many clips, having watched probably all the ones yet
shown. The evidence presented here looks convincingly like it was "painting a target", similar to weapons used today (one can be found in
America's Army game), and indeed this could be used to guide something to impact.
