Speaking of that, did anyone else see the report regarding the FLIR camera they used following the Boston bombing to locate the one suspect hiding in the boat? It was an interview with the fellow who invented/developed the FLIR technology which is commonly installed now on search and rescue aircraft.

Anyway, two things that the FLIR CANNOT "see" through are CLEAR GLASS (?!) and CANVAS tarps. So, most people wouldn't consider "hiding" behind a pane of clear glass, but if the boat had been covered by a canvas tarp instead of the cheaper and more common "plastic" cover they wouldn't have been able to spot the man hiding in the boat. Interesting, huh?
