However, according to the U.N., Iraq's most effective biological weapons platform was a helicopter-borne aerosol generator that worked like an insecticide disseminator (perhaps intended for domestic use or against Iranian troops close to the Iraqi border).
It also occurs to me that the news helicopters so commonly flying over our cities could pose a real threat one of these days. I hope the FBI is monitoring helo sales and that news organizations have instituted some kind of increased security.
