Atta was working for the US military?

From rigorousintuition:

....for an agency which, before 9/11, appeared clueless that members of al Qaeda were training at flight schools, the FBI inexplicably and immediately knew, upon the attacks, which flight schools al Qaeda members had attended. And this was long before suspects should have been identified.

Venice Florida's Huffman Aviation was the principal flight school used by Mohammed Atta and associates, though used for what is a good question, as Atta was already a pilot. (The best answer may be a familiar one to students of deep politics: trafficking narcotics.) A former Huffman manager told investigative journalist Daniel Hopsicker that a carload of FBI agents pulled up outside his house in the middle of the day, on the day of the attack.

"They were outside my house four hours after the attack," he says in Welcome to Terrorland. Hopsicker writes that "they didn't strong-arm him to make him think harder and cough up some useful leads, but to ensure he kept his mouth shut."

The shaken source had quit Huffman because he'd found the workplace to be something else than he'd expected. Something, well, spooky: "I had to leave and get out. I wish I didn't know as much as I know. I told them they had nothing to fear from me."

What did he know?

"These guys [Atta et al] were double agents.... I gleaned early on that the operation I was working for had government protection. They were let into this country. How did the FBI get here so soon? Ask yourself: How'd they get here so soon?"

And note: when he says "here," he doesn't mean Huffman Aviation; he means his own house. So, only four hours after the attack, the FBI didn't merely know enough to visit Atta's flight school; it knew enough to visit the home of a former employee of Atta's flight school who had quit because he suspected Atta and his cadres were double agents. It wasn't investigating the attacks, it was intimidating witnesses.
