He does NOT need to have the laser on the spot of several seconds. The laser only needs to be on the spot turning the last few seconds of the count down.

So since the laser only needs to be on the spot during the last few seconds, what guides it prior to that?
During the ballistic phase, the weapon continues on the unguided trajectory established by the flightpath of the delivery aircraft at the moment of release.
The missile, bomb, etc. is launched or dropped somewhere near the target. When it is close enough that some of the reflected laser energy from the target reaches it, a laser seeker notices which direction this energy is coming from and aims the projectile towards the source.

Anyway, on the bottom right you will see a count down. The first count down is the launch count down. When it reaches 0, it starts over, this is the count down until impact. During the impact countdown, the laser operator has the ability to change his target to whatever he wants, within the area.

I hope that is clear. (SNIP)

As long as the projectile is in the right general area and the laser is kept aimed at the target, the projectile should be guided accurately to the target.

Nope, it's not clear, becuase the video you just posted shows the laser on the target for the last 30 seconds or so. It's a moving target, and the person aiming clearly follows the group along the road until impact.

KEY WORDS: and the laser is kept aimed at the target

excellent observation innocentbystander.
This is a point he's just not getting though.
They do NOT turn off the laser, so you could argue that they had the laser pointed on a target since takeoff.
Do you notice how many times he changes his target? From a building, to people walking, he changed his target.
Just because you see him aiming at a target for a few seconds longer, doesn't mean it is necessary. They have the ability to change there target within the last few seconds.
I thought that was clear, obviously it wasn't.

Actually it was a HORRIBLE observation, because the people are walking, and it is a "moving target". That is proof that the laser does not need "to be a still as possible".
Good Grief!

IWY, Let me be as clear as possible. I'm not saying the laser has to be still. I'm saying that the laser should be aimed at the target for more than the last 4 seconds before impact.

Well how about this... The targeting laser was a last ditch effort by the US government to take down the plane before it hit the building but they couldn't lock on quickly enough. That would be what you see dance across the building.
Even though it's not a laser, it's just a fun thought about presumption of guilt
Well, that would mean the entire 9/11 Commission Report is a lie.
That would also mean NORAD lied about its fighter jets.

Not necessarily. Maybe they were trying to use a version of the ABL system.
Boeing completed initial modifications to the 747-400F in 2002, culminating in its first flight on July 18, 2002 from Boeing's Wichita, Kansas facility.
