Unless it was a rerun, an hour ago CNN said that the FBI (FAA?) is prohibiting cropdusters from flying again tomorrow. The newsperson said at least two times it was an "update," so I'm assuming that wasn't old news. They said that so far it's only for tomorrow. What kind of sense is that? Either there's a problem or there's not!
This next one is probably the best article so far. The target audience is emergency room physicians and it was published in a peer-reviewed journal in Feb, 2000. The author, G. Moran, has appeared before Congress, if I'm remembering correctly. (I'll double-check and come back to correct that if I'm wrong.)
