CAPE KENNEDY - Two pieces of the space shuttle Challenger that blew up 11 years ago have washed up on a Florida beach. One of the pieces, measuring 2 by 5
metres, is the largest chunk of Challenger debris found on a beach. It will be taken back to Cape Kennedy for examination.
On January 28, 1986, Challenger exploded one minute and 51 seconds after lift-off, killing all seven astronauts on board.
