This first one is a good one:
Why Batman Could Exist--But Not for Long
So You Wanna be Batman, Huh?
The reason to read that second one is because the last paragraph brings up an easily forgotten point:
The truly impossible piece is the notion that Batman could have such a small operation. The kind of vehicles and accutraments Batman favors are temper[a]mental creatures in real life, and even prototype level fabrication efforts that are highly automated require quite a large production crew. A back office of scores to a couple of hundred people would be necessary to keep the operation in working order, and at least a dozen o[r] two would have to have such a regular and working relationship that they would have to know exactly what they were doing for whom.
