Cargo ship crash details revealed by crew member who says vessel rammed tanker "out of the blue"

London — An American man who said he was among the crew on the MV Stena Immaculate tanker when it was hit Monday by a cargo ship, causing both vessels to burst into flames off England's east coast, told CBS News the other ship "came from out of the blue" and rammed the Stena.

The man, who asked to remain anonymous because he wasn't permitted to speak with media about the crash, said the Stena had been anchored on the spot where the collision occurred and had relayed its coordinates, meaning all other vessels in the area should have known its position.

He said was near to the part of the Stena Immaculate where the Portugal-flagged container ship Solong made its impact, and that he had only seconds to react when he heard shouts to brace before impact. Then, all of a sudden, he said "a massive ship came from out of the blue."
