Investigators say whatever went wrong happened within the span of five minutes, between the time the ship pulled away from a dock and hit the bridge.

Two crew members aboard a Mexican Navy sailing ship died on Saturday night when the vessel drifted into the underside of the Brooklyn Bridge, smashing its masts and rigging.

The training vessel Cuauhtemoc could be seen approaching the iconic bridge over the East River, stern-first, before two of its masts hit the bridge.
