U.S. investigators laid out a timeline showing the Cuauhtemoc, a Mexican naval vessel, was underway for less than 5 minutes before its masts crashed into the historic span of the Brooklyn bridge, and radio calls indicating it was in distress went out only 45 seconds before the deadly collision.

The Cuauhtémoc remains docked off Pier 37 as work crews shore up the ship’s three splintered masts before it taken to a nearby salvage yard.

The Cuauhtémoc, a training ship used for the Mexican Navy that crashed into the Brooklyn Bridge on May 17, was embarking on an annual transcontinental journey that marks the completion of cadet training.
