Flight training for Muslim terrorists in America has a mixed track record. On the one hand, there’s 9/11 and nearly 3,000 dead.

But on the other hand, think of all the ones we trained who didn’t fly planes into skyscrapers. Yet.

So in that spirit, a special agreement has been signed for Qatar, which apart from serving as the state sponsor for the Muslim Brotherhood and its Hamas arm, also harbored Khalid Sheikh Mohammed: the mastermind of 9/11.

American officials say the FBI and CIA just missed capturing the al Qaeda leader believed to have organized the 9/11 attacks — and now believed to be planning a new attack against Americans — because it appears he was protected and tipped off by a member of the royal family in Qatar, Abdullah Bin Khalid al-Thani.

In 1996, the FBI tracked Mohammed, under indictment on charges of terrorism, to Qatar’s capital city, Doha, and was within hours of capturing him.

Cloonan, who was the lead FBI agent on the case, said a specially equipped government executive jet, complete with blacked-out windows, was standing by to transport Mohammed.

“We had located Khalid Sheikh,” Cloonan told ABCNEWS. “We were prepared to fly the plane in and to take him out.”

But Cloonan says Mohammed was tipped off shortly after Qatar officials were told of the plan and headed for the airport.

There have been reports that even Osama bin Laden was allowed to pass through Qatar.

So why not train their pilots? What’s the worst that could happen?
