In almost every movie Titanic when the collision shows the Titanic trying to do the reverse to avoid the collision and some films shows that this is a mistake. At the helm of the size navio.do ship and machinery of the time, the engines of an Olympic-class ship needed just over a minute to stop and probably another to reverse speed, the Titanic had only 40 seconds since was given the order to the fatal collision. This indicates that at the time of the collision, the Titanic's propellers were spinning very quickly. In the film appears that in less than 40 seconds, the ship slowed, braked, reversed the direction of the helices and was back at full power. Surely this spectacular scene is of grave technical error.
