An idea -- With all of the relatively low-cost / incredibly-small digital cameras (motion and still) now available, is it realistic to think of inserting one of these small camera lenses into an aircraft engine's cylinder (through a spark plug hole) and taking pictures of the valves? Sort of like a poor-man's boroscope. I've seen digital camera lenses advertised that appear smaller than the typical spark plug hole. Can any of you electronic wizards out there give this a try and report your findings?
