Osama bin Readin' some Clancy

After 9-11, several reporters pointed out that in the end of Clancy's novel Debt of Honor, a suicide pilot crashes a plane into the capitol, killing most of the government. It was implied that Osama got the idea from the book. There's even some nuts out there that think the idea was planted by the US military.
Now, a report from the Department of Homeland Security warns of dangers from lazers

In certain circumstances, if laser weapons adversely affect the eyesight of both
pilot and co-pilot during a non-instrument approach, there is a risk of airliner
crash.

In other words, by shining a bright light in their eyes so that they can't see when they land. An idea that is used in a Tom Clancy book, in fact the same one with the suicide pilot.

Sounds like the terrorists went out to read the book that inspired the events, and got some more ideas.
