I just don't get that size of flashlight, we have far superior, while cheap, like a few bucks cheap...aka...pilot style. One AA and you are set for 6 months!!!

Then again I don't understand being a wanna be pilot, while being a doctor on a pilot forum, bashing our programs when you can only afford a 182. I flew for a neurosurgeon and he could afford a king air plus a bunch....must be a sorry cardio doc I guess....
