The Francis Scott Key Bridge disintegrated from the impact of a container ship.

984-foot vessel slammed into a bridge support at a speed of 8 knots, which is about 9 mph.

Rescue crews using sonar detected at least five vehicles in the frigid 50-foot-deep water.

Investigators quickly concluded that it was an accident and not an act of terrorism.

President Joe Biden vowed to rebuild the bridge and send federal funds.
