Hello; The boat hitting the bridge was the fault of the bridge operator, not the boat captain. The bridge was lowered as the boat was passing under. The ship losing its bridge deck to the lowering rail bridge was not the fault of the captain of the vessel. It was the fault of the bridge operator who began lowering the bridge too soon in an attempt to get off work early. Not fair to criticise the ship captain at 1:53, this is a well known clip where in fact the bridge master made a huge error and began lowering the bridge before the ship had passed. Also, at 5:40 the logs are intentionally dropped over the side, this is a common maneuver when shipping lumber. Huge ships engine fails in bad weather and the ship breaks in half while against rocks and you say this is the worst employee mistake! Trying to take one trip instead of three was what my father called "Taking the Lazy Man's Load." It usually meant you would try to take three times what you would normally try so you would only make one trip instead of three. And usually that single trip would end in failure while the three single trips would be spectacularly successful.
