" Then I’ll wind it up as fast as I can,” Wagoner said. “What it all comes to is that the whole structure of space flight as it stands now is creaking, obsolescent, over-elaborate, decaying. The field is static; no, worse than that, it’s losing ground. By this time, our ships ought to be sleeker and faster, and able to carry bigger payloads. We ought to have done away with this dichotomy between ships that can land on a planet, and ships that can fly from one planet to another. "
