Al Queda in Cropdusters

BBC: The Federal Bureau of Investigation (FBI) recently confirmed that Mohammed Atta, one of the suspected hijackers who is believed to have piloted a jetliner into one of the twin towers, was acquiring knowledge of crop-dusting aircraft prior to the devastating attack.

Atta was reported to have visited an airport in Florida where he enquired how far crop dusters could fly and requested details of their carrying capacity.

Debora MacKenzie, NEW SCIENTIST:  The Al-Qaeda group suspected of the 11 September terrorist attacks is allied to Iraq, and to Chechen rebels in the former Soviet Union. Iraq and the Soviet Union both developed anthrax weapons consisting of aerosolised spores that would cause pneumonic disease. The group is also known to be interested in bioweapons.

Paul Ewald, biologist, Amherst College, author of Plague Time:  If this attack was caused by the Al Qaeda group—and I think that's the best explanation, given the evidence available - this small release would be most useful as a demonstration that they have anthrax on U.S. soil.

Smart terrorists would have made or obtained larger quantities of the stuff and stashed it, probably (if they're smart) before setting off alarms by sending out a few grams. Later, with the potency of their weapon proved, they could mount, or threaten to mount, a much larger attack.

Larry Bush, 1st to diagnose Anthrax: When dispersed in the air as 1-to-5-μm paticles, B. anthracis endospores may pose a risk even over large geographic distances. After an accidental release of endospores from a military biologic-weap-ons facility in Sverdlovsk, Russia, cases of anthrax in humans occurred as far as 4 km from the site, and cases in animals occurred as far as 50 km away.

U.S. Air Force Colonel Randy Larsen (Ret).  In an Oct. 21 progress report, this bipartisan board cautioned that “a one-to two-kilogram release of anthrax spores from a crop duster plane could kill more Americans than died in World War II”. The commission’s crop-duster scenario was conceived after Americans discovered two Afghan anthrax laboratories.  “The 9/11 Commission Report” says Jemaah Islamiah agent Yazid Sufaat “would spend several months attempting to cultivate anthrax for al-Qaida in a laboratory he helped set up near the Kandahar airport.”

Interestingly enough, Sufaat was captured thanks to information that American interrogators gleaned after waterboarding KSM. Had America not dampened KSM’s nose, U.S. soldiers or civilians already might have had Sufaat’s anthrax up their nostrils.

Stan Bedlington, a ret. CIA, Counterterrorism Center:   Frankly, when I heard the news, I thought, 'It's got to be biochemical'.  This is frightening enough and yet, you could take a small plane and sprinkle anthrax over New York City and wipe out half the population.
