LOL, wow, reading is not your best asset. Here let me point out what you missed. "almost-perfectly parallel beam". You want to know why it is NOT perfect? Because of the lenses used to create the beam. No matter what lens setup you use, you will ALWAYS have "focal length" issues.
1. Almost perfectly = not perfectly parallel beam.
2. Yes, laser lights CAN be focused down to a tiny spot as small as a single wavelength, because lasers have "photons" traveling in one direction like Direct Current. Flashlights however, are Alternating Current streams of "photons". If you used lenses to focus a laser, the "focal point" of the laser could be smaller than a flashlights "focal point" just because the laser "photons" are in a single file line.
No matter what though, you have to manipulate the glass lenses in order to get this tiny stream of light. Not only that but you have to know the distance you are away from the target to find that focal point. If you are to close, the laser will be bigger, if you are to far, the laser will also be bigger.
Thats a good question, and I will tell you. The TRACKING LASER can be used to measure distance. How? Simply by determining the size of the laser when it hits an object. If you have a not perfectly parallel beam of laser, you can use that to your advantage to find the distance of an object with an equation. If for instance the TRACKING LASER made a "1 story tall" laser circle, you can use that measurement to find out how far or how close you are to the object the laser is hitting.
If the "focal point" made a laser dot that is known to be 1 inch in diameter, at 100 feet. Then what would that mean if the laser was 2 inches in diameter when it hits the object? That would probably mean the laser is 100 feet away from the focal point. Meaning you are 200 feet away from the object.
So you can see why you wouldn't want the tracking laser to be focused, it will help determine the distance of an object.
The weapon laser though, that's the one we DON'T see in the video. That is the one you would want to focus, depending on how close you are.
So once again you're saying that the further from an object, the larger the laser dot gets. Well then why isn't there a giant laser dot on the moon?
Why wouldn't they start with a 1mm dot at distance and work up to a 50mm dot instead of a 12 ft dot?
Oh and by your own posts, you mention that when the dot hits the building, it turns visible. Why have a 12 ft tall SPOT LIGHT on the side of a building surrounding by thousands of witnesses when you could have a 50 millimeter tall dot.
Also, here's how you use lasers to measure at long distances.
Time-of-flight measurements (or pulse measurements) are based on measuring the time of flight of a laser pulse from the measurement device to some target and back again. Such methods are typically used for large distances like hundreds of meters or many kilometers. Using advanced techniques, the time-of-flight method allows to measure the distance between earth and the moon with an accuracy of a few centimeters. Typical accuracies of simple devices for short distances are a few millimeters or centimeters.
Do you notice anywhere where it says they measure the size of the laser dot?
Oh yeah, they could have used remote piloting, but theoretically that is the biggest mistake anyone would make. Of course, when you remotely pilot an aircraft, you have multiple electronic signals traveling over the airways.
In order to fly the jet you need a video feed coming from the jet. This video feed can be picked up by ANYONE with the right equipment, especially the News Media equipment. Also, flight controls, and other signals are over the airways too, all of these could be detected and picked up by other sources on accident. Just like how Russia and other radio experts were able to listen in during the entire "moon landing" of NASA.
A laser guided jet though, all the risk you take is someone having the right camera in the right place. There is no electronic signals that could possibly be recorded. The jet sees the red dot, the jet flies to the red dot. The whole "you don't need to paint the target' is a moot point, because jet's don't fly the same as Hellfire missiles, they need to be guided differently, and the best bet would be manual laser designating, instead of automatic laser designating.
It is however still possible that the jet WAS remotely piloted, hence the reason the government lies to us about the "flight recorders" from the jets that hit the WTC's. That would mean the laser is something else, a new type of weapon perhaps.
All I know is, that video DOES have a laser in it.
Once again, its all about how you focus the laser. Since NASA know's how far away the moon is, they can actually find the "focal point" of the laser and point it at the mirror. However, if they didn't know the distance, it would be really hard to focus the laser on that object.
Laser's do not travel in a perfect parallel line no matter what your imagination thinks.
The TRACKING LASER can be used to measure distance. How? Simply by determining the size of the laser when it hits an object. If you have a not perfectly parallel beam of laser, you can use that to your advantage to find the distance of an object with an equation.

The ABL tracking laser is described as follows
The ABL is the first airborne megawatt-class laser weapon system. The ABL is a specially configured 747-400F aircraft, designed to autonomously detect, track and destroy hostile ballistic missiles during the boost phase.
The high-power laser is coupled with a revolutionary optical system capable of focusing a basketball-sized spot of heat that can destroy a boosting missile from hundreds of miles away.
The laser and optical systems are controlled by a sophisticated computer system that can simultaneously track and prioritize potential targets.
Please visit the link provided for the complete story.
Notice the key points:
BASKETBALL-SIZED SPOT
HUNDREDS OF MILES AWAY.
The problem once again, is that you don't read correctly. First you say "The ABL tracking laser is described as follows", then you proceed to tell use that the weapon lazer is basketball-sized.
Do you know the difference between the tracking laser and the weapon laser?? If it wasn't already obvious in my first post, I have claimed that the video of the "orb" is the tracking laser, and NOT the weapon laser.
So, you are either not reading things correctly, or purposely fogging information to make people believe you.

If lasers dispersed as much as you think they do, the laser would be the size of the moon by the time it got to the moon.

This is funny. Your own answer above contradicts your big dot theory.
You don't need to know a distance you are away from the target to get a fine point. If the pinpoint focal point is known you get a sharper point. Think of an inverse cone getting smaller the farther it gets with a dispersion offset by the ALMOST PARALLEL laser.

Once again if you had read anything in this thread, you would know that you don't need "night shot" or "infrared mode" to see the infrared with a normal camera. Heck I even posted a link about "infrared" and it even shows a normal camera picking up infrared.

You have claimed that the tracking laser fired at the building expanding as it got further from the source. I'm showing you an example of just the opposite of how you think it works.
Originally posted by jfj123
OK lets clear this up right now. Anyone here have a "normal camera" they can use to take pictures/video of their infrared remote beam? If you could and post them, that would be great. That way we'll know one way or the other for sure and be able to completely end that portion of the debate.
Thanks in advance
You see, I never once said the laser in the video was the weapon laser. The laser in the video is the tracking laser. You confusion is what messes up your reality.

DID THE AIRBORNE LASER HEAT UP THE SIDE OF THE WTC'S SO THE JETS CAN SIMPLY SLICE THROUGH THE EXTERIOR STEEL LIKE A COLD KNIFE THROUGH WARM BUTTER??
then there's this one
DID THEY USE THE AIRBORNE LASER TO "SHOOT DOWN" FLIGHT 93??
Here he is again talking about the laser weapon
A solder gun, and solder, is basic physics. A welder welding metal, thats basic physics. Neither of those devices need much time to heat up a metal on direct contact. Besides, I don't think a laser of this size acts in any way close to "basic physics".
oops, here he is again talking about the laser weapon
Thats because you are a civilian and do not have the full information. When you can prove that it has not passed research stage, then maybe your thoughts hold water. At this current day, I have video of working laser weapons. They are real. I actually have video proof of Rumsfeld talking about direct energy weapons, and how "normal" procedure for new weapons is to develop, test, employ. Yet he also says sometimes they use things even if they are only in "test" stage.
By the way, there are alot of other instances of 11 11 talking about the laser weapon.

11 11,
Here's where you finally admit that the "laser" on the building isn't a weapon.
Ok, so it wasn't the ABL. Spicing up theory is always fun. But still, look at the evidence of a laser light on the WTC. It disappears when the jet hits the WTC, and comes back. Maybe the laser was blocked by the jet, and with that information we could find an approximate angle of the light source.
