Why the choice of ZERO as the starting number?
"OK Bob you drop on Hangar one"
"This is Mike, I thought I was droping on the first hangar?"
"You do Mike. You're dropping first, on the first Hangar"
"But you just told Bob to drop on Hangar 1"
"Hangar 1 is the second Hangar."
"Whuh?"
"Hangar one is the Second Hangar"
"What hangar is the first Hangar?"
"Hangar 0"
"So Zero is 1?"
"No, Zero is first, not one."
"Whuh?"
"Oh crap we missed the drop!"
