This image, made using a laser mapping technology called LIDAR, was taken on September 17, 2001. It shows a 3-D model of the rubble left behind in lower Manhattan following the attacks on the World Trade Center.

Minnesota Public Radio's Paul Tosto has a really interesting peek into the way mapping techniques like LIDAR were used to help rescuers and clean-up crew understand the extent of the damage, look for survivors, and rehabilitate the area around the disaster zone.

The Library of Congress work also includes data from a a thermal sensor flown at 5,000 feet over Ground Zero that provided images to track underground fires that burned for weeks at the site.

It's worth remembering that Google Earth didn't exist back then. The ancient science of cartography has been reborn with the technology of the last decade. Let's hope it's not called on again to map destruction.

Four present and past security screeners at LAX took 22 payments of up to $2400 each to let large shipments of coke, meth, and pot slip through baggage X-ray machines. Oh, we are so very, very shocked.

In one incident detailed in the 40-page indictment (Link), screeners plotted to allow eight pounds of crystal meth to get through—then one of them ducked into an airport men's room where he was handed $600, the second payment for that delivery.

Earlier this week on Boing Boing, Cory blogged about a 95-year-old Air Force veteran who was robbed of $300 at a TSA checkpoint. After picking on the elderly, today the TSA is bullying children. A 4-year-old girl who was upset during a TSA screening at the Wichita, KS airport was forced to undergo a manual pat-down after hugging her grandmother. Agents yelled at the child, and called her an uncooperative suspect.

Nope, we're not making this up.

The child's mom, Michelle Brademeyer of Montana, shared the incident in a public Facebook post last week, and the story has since spread widely.

“They didn’t explain anything and she did not know what was going on,” the grandmother told the Associated Press. “She saw people grabbing at her and raising their voices. To her, someone was trying to kidnap her or harm her in some way.”

Think the TSA has apologized? Nah. The agency is defending its agents, despite promised changes in operational standards to "reduce pat-downs of children."

Glenn Greenwald rounds up a number of reports related to the killing of al-Awlaki's 16-year-old son by an unmanned aerial drone from the US:

Two weeks after the U.S. killed American citizen Anwar Awlaki with a drone strike in Yemen — far from any battlefield and with no due process — it did the same to his 16-year-old son, Abdulrahman al-Awlaki, ending the teenager’s life on Friday along with his 17-year-old cousin and seven other people.

Still think that something other than a mere plane crash brought down the World Trade Center towers? According to a Norwegian materials expert, you may be right. Just ... you know ... not in the way most Truthers probably expect.

Christian Simensen thinks the Twin Towers were ultimately felled by a thermite reaction.

"If my theory is correct, tonnes of aluminium ran down through the towers, where the smelt came into contact with a few hundred litres of water," Christian Simensen, a scientist at SINTEF, an independent technology research institute based in Norway, said in a statement released Wednesday.

"From other disasters and experiments carried out by the aluminium industry, we know that reactions of this sort lead to violent explosions."

Given the quantities of the molten metal involved, the blasts would have been powerful enough to blow out an entire section of each building, he said. This, in turn, would lead to the top section of each tower to fall down on the sections below.

The sheer weight of the top floors would be enough to crush the lower part of the building like a house of card, he said.

I honestly don't know how plausible an idea this is. It sounds reasonable to a layperson, but I'm curious what those of you with more engineering expertise think.

The AFP has a write-up about the theory. There's also a more-detailed explanation on the website of SINTEF, the Norwegian research lab where Simensen works. Finally, this appeared in the trade journal Aluminum International Today, and they've got an email address where you can request a copy of the story.
