"By 1973, we had a space station, the Skylab, and we had
multiple probes going up to planets. So, all this wonderful stuff
happened in 10 to 15 years," he told the BBC. "About that time,
there should have been enormous initiatives to make it affordable
for people to fly in space, not just a handful of trained NASA
astronauts and Russian cosmonauts. If you asked NASA in those days
how long will it be until it is affordable so that I can fly, the
answer would be, 'we're working on it and in 30 years there will be
affordability.' If it is (still) 30 years, I will 90 and will a guy
who is 90 get to fly?"
