"Indicators of Terrorist Activities ... Internet Café" on sheriff's public site

I was not aware that enough terrorists had been apprehended to compile a checklist of suspicious activities.

In particular: http://www.osceola.org/sheriff/113-19137-19144/hobby_shop_te...

Can someone post articles about hobby shop terrorists? Did any of the 9/11 Terrorists purchase large R/C airplanes to practice? I can't find any answers in Google. Or Bing.
