"I think the United States by giving up the shuttle is making a serious mistake because technologically, it's the most advanced space vehicle in the world, and really there is no reason not to continue to fly it," former Johnson Space Center Director George Abbey said.
In Moscow, Abbey told us NASA should keep flying the shuttle indefinitely and in the meantime build a new space vehicle based on the technology it knows — winged shuttles. He insists the new rockets that NASA has planned are a step backwards.
"Here we've got really the greatest vehicle in the world, and we are giving it up," Abbey said. "Don't start a whole new type of architecture that causes you to go back and start flying capsules, which gave up many years ago."
