Challenger disaster's 25th anniversary


The US space agency Nasa has held a day of remembrance for astronauts who have died in the line of duty, particularly the seven who perished in the 1986 Space Shuttle Challenger disaster.

It is 25 years since the shuttle exploded 73 seconds after launch at an altitude of 14,000 metres (46,000ft), killing all on board.

In a ceremony at Arlington National Cemetery in Virginia, a wreath was laid in tribute to the seven people who lost their lives.

The BBC's Andrew North reports.
