And the findings are consistent with the scenario I laid out a few hours ago, which I seem to have correctly recalled. Keep in mind that the collision with the bulbous bow is a downward impact; the bulbous bow sticks out and the visor falls onto it. However, if that prevents the bow from sinking immediately, then the sudden increase in hydrodynamic drag that occurs as the ship pushes the visor ahead of it will produce the sudden sense of deceleration that is reported by the witnesses.
There is no doubt the bow visor fell off. But what happened immediately before it fell off?
