Also good thread link. The link mentioned is great, with a tremendous amount of information and links. I've had a hard time locating anything searchable about Bojinka, so this provides a quick link to that good thread.
I'm highlighting one item out of that grand link:
http://www.washingtonpost.com/wp-dyn/articles/A10840-2001Sep22.html
- an item about the ongoing problem with the flight schools. If full-motion flight simulators were export controlled and required an export license, it'd be a lot harder for Middle Eastern terrorists to gain access to these, and they'd be subject to much more screening, even to access training and simulators in the US. But for some reason this simple and easy-to-implement legal tool isn't being put into place. See http://www.bxa.doc.gov.
