Australian PM says confident of position of MH370's black box

SHANGHAI (Reuters) - Australian Prime Minister Tony Abbott said on Friday that searchers were confident they knew the position of the black box flight recorder from a missing Malaysian airliner, but cautioned this was not the same as recovering wreckage.

"We are confident that we know the position of the black box flight recorder to within some kilometres (miles)," he said in a speech in the Chinese commercial capital Shanghai.
