saying that a giant death laser from Lord Xenu's spaceship brought down the towers is just"

You vouch for that, right?

Unfortunately, we have invented microwave weapons -- quite some long time ago.

We also have smaller nukes.

And certainly Thermite was involved in the bringing down of the WTC --
a specific brand which is used by the military.

EXPERTS in demolition confirm that what you saw was "demolition" of the WTC towers --

And if you watch some of the tapes you will hear one or more anchors reacting to it
and commenting that it looked like "demolition."

You might also like to give some thought to how the hijackers just happened to know
that on 9/11 our military had insanely arranged for four military exercises -- to be
run simultaneously beginning at 8am that morning -- at least two of them based on
skyscrapers being attacked by hijacked jetliners?

And had also insanely arranged for NORAD to be be put out of action?

And if your science says that an aluminum plane can cut thru steel like butter, I'd
go hit the books again.

On the right is the Zenu microwave gun for crowd control 

The ADS works by firing a high-powered beam of electromagnetic radiation in the form of high-frequency millimeter waves at 95 GHz^[8] (a wavelength of 3.2 mm). Similar to the same way that a microwave oven heats food, the millimeter waves excite the water and fat molecules in the body, instantly heating it and causing intense pain. (Note that while microwaves will penetrate human tissue and remove the water to "cook" the flesh, the millimeter waves used in ADS are blocked by cell density and only penetrate the top layers of skin, so it will not damage human flesh^{[citation needed]}.) However DNA damage caused by these weapons is unknown and could lead to malignant cancers in operators and targets. Such is the nature of dielectric heating that the temperature of a target will continue to rise so long as the beam is applied, at a rate dictated by the target's material and distance, along with the beam's frequency and power level set by the operator. Like all focused energy, the beam will irradiate all matter in the targeted area, including everything beyond/behind it that is not shielded, with no possible discrimination between individuals, objects or materials, although highly conductive materials such as aluminium cooking foil should reflect this radiation and could be used to make clothing that would be protective against this radiation.^[9] As demonstrated on Discovery Channel's "Future Weapons", all living things in the target area receive a similar dosage of radiation.

A spokesman for the Air Force Research Laboratory described his experience as a test subject for the system:

"For the first millisecond, it just felt like the skin was warming up. Then it got warmer and warmer and you felt like it was on fire.... As soon as you're away from that beam your skin returns to normal and there is no pain."

Many aspects of the research are classified, but AFRL has taken care to include independent evaluation of the maker's claims in the formal test program. According to public releases, there have been over 10,700 "shots" by ADS,^[10] and has been deemed safe for use. A Penn State Human Effects Advisory Panel (HEAP) has published findings of research showing

• no significant effects for wearers of contact lenses or other eyewear (including night vision goggles)
• normal skin applications, such as cosmetics, have little effect on ADSʼs interaction with skin
• no age-related differences in response to ADS exposures
• no effect on the male reproduction system
• developing cancer from exposure is "very unlikely"
• no deleterious effect on birth defects
• the limit of damage was the occurrence of pea-sized blisters in less than 0.1% of the exposures.

The HEAP has concluded that ADS is a non-lethal weapon that has a high probability of effectiveness with a low probability of injury.^[11]

The ADS is currently only a vehicle-mounted weapon, though U.S. Marines and police are both working on portable versions.^[12]
