'Pioneer' astronaut John Young dies

US astronaut John Young, who flew to the moon twice and commanded the first ever space shuttle mission, has died aged 87, Nasa said.

“Today, Nasa and the world have lost a pioneer,” agency chief Robert Lightfoot said in a statement.

Young was the only person to have flown missions on the Gemini, Apollo and space shuttle programmes.

He also once famously smuggled a corned beef sandwich on to a space flight as a gift for a fellow astronaut.
