The solution was, in my mind, to have an integrated air and ground system, which had never been done. And to operate not on a linear basis, where you try to take things from one point to another, but operate in a systemic manner. Sort of the way a bank clearing house does, you know? They have a bank clearing house in the middle of all the banks and everybody sends someone down there and they swap everything around. Well, that had been done in transportation before: the Indian post office, the French post office. American Airlines had tried a system like that shortly after World War II. But the demand side and supply side had really not met at an appropriate level of maturation.
