More from the BBC that seemed worth sharing with readers.
From here, an extract:
Work to line the top of an escape shaft with metal tubing is expected to finish in the next few hours at the mine where 33 men are trapped in northern Chile.
A winch and pulley will be installed and the shaft tested before the rescue begins, it is hoped, on Wednesday.
Amid the final preparations for the rescue the Chilean health minister said some of the miners were gallantly insisting they should be last to leave.
And some wonderful pictures on the BBC website here.
