PORT FOURCHON, La. (AP) An intense search is on in the Gulf of Mexico for 11 workers missing after an oil rig explosion. The Coast Guard search has been going on all night long.  They say the best chance for finding those workers alive, is if they were able to reach a covered lifeboat.
A total of 126 workers were aboard that rig when it blew up.  About 100 workers made it onto a supply boat, which just reached the shore early this morning.  Seventeen of those workers were taken by air or sea to hospitals.  Four are in critical condition.

This morning, many survivors are being reunited with their families at suburban New Orleans hotel.

Workers didn't get any warnings about a problem before the explosion.  However,  the focus right now isn't on the investigation, it's on finding those missing people.
