Didn't you know the rivets holding the ship together were absolute crap, causing the metal to "peel off" easier?
Isn't it something that the rivets, combined with the speed it was going (to make it to New York in under six days) and the poorly designed watertight compartments could cause a ship to sink?
Would you believe that first-class flyers would get to ride on Rainbow Dash and everyone else had to ride on Derpy?
