From the New York Times:
The Coast Guard said on Wednesday that BP had been forced to remove a cap that was containing some of the oil gushing into the Gulf of Mexico.
Adm. Thad W. Allen of the Coast Guard said that an underwater robot had bumped into the venting system. That sent gas
rising through vent that carries warm water down to prevent
ice-like crystals from forming in the cap.
Mr. Allen said that the cap had been removed and crews were
checking to see if crystals have formed before putting it
More to come.
