Obviously you did not read the article.
Well to be honest I didn't until you mentioned it : )
Here is the money quote "How did Mr. Kucharek know that Yavuz Berke wouldn't toss something out of the window of that stolen plane? He was right over the bread basket of this country. A little something in powder form would have wiped out a goodly chunk of livestock and people. How did they KNOW he didn't have that capability?"
Hmm because it doesn't exist? What little bit of something thrown out over vacant farmland could wipe out a chunk of livestock and people? I don't think I will hold my breath waiting for an answer. Ebola? Anthrax? Ricin? I don't think so. It is hard to think of a worse delivery method.
