A while ago in class, a scheme concocted during WWII to make use of bats as a delievery system for inendiary devices was mentioned. I remember listening to a bit of a show on the History Channel some time this past year concerning the project, but I couldn't recall much, other than the project had been scrapped, due to an embarrasing accident. So, in order to find out more, I did a bit of digging around, and came up with the following links... The first link concerns the project itself. The second link is an interesting little tidbit that makes mention of the project.
The final link appears to be a page owned by a drama group who wrote/ran a play based on the project.
