skywalk open to VIPs today
more on the grand canyon skywalk -- open today to VIPs like former astronaut Edwin "Buzz" Aldrin.
"I felt wonderful, not exactly floating on air ... but a vision of hope for the future," [Aldrin] said afterwards, quoted by Reuters news agency.
The BBC's Andy Gallacher, who also went on the Skywalk, says the glass beneath his feet was so clear it was like walking on a cloud.
