No need for a drone -- a private plane operated by a licensed pilot with a sprayer could do the same thing. Read the chilling, very realistic scenario published here:

If It Happened Here (mine: freerepublic.com mentioned in HYPOTHETICAL story about LA Anthrax attack)

Yeah I would agree that a light plane could do it. But you may have trouble getting one outfitted with spray equipment. There is a general avaition airport nearby and they are on high alert. People inspect the planes before they take off. Getting the toxic stuff loaded would not be simple.

A drone could be dissassambled, stored in a ship container, assembled, loaded with toxin from the container, launched and deliver.

But either could work. I think the drone is easier. Especially if your target is Isreal, Kuwait or Iran.
