George Pierce Baker Aviation Accident Report: Pan American Flight 203 (1942)

However, it appears that Captain Lorber, through misjudgment, landed the airplane in an unduly nose-low attitude and while it was making some leeway. The surface of the water of San Juan Harbor was slightly disturbed in some areas and glassy in others. The existence of a glassy surface is frequently conducive to misjudgment of height above the water as well as, to a lesser extent, misjudgment regarding the altitude of the aircraft. Another factor tending to lessen depth perception was the presence of a bright moon nearly directly overhead.

Serious consequences may result if the airplane happens to be turning or if it has any leeway or side motion relative to the water.
We are forced to the conclusion, therefore, first, that the subject aircraft was landed in an unduly nose—low attitude, and second, that at the time of first contact while in that attitude, it was moving sideways relative to the water. It appears from the record that there were no extraneous turning forces which might have been caused by non—uniform application of power or by faulty rudder tab setting.

The landing launch is carefully located with respect to the landing area lights in order that it can assist in marking the landing area by the beam of its search—light and in order that it can be as close as possible to the point at which the airplane first makes contact with the water. By landing in the wrong direction Captain Lorber made it impossible for the landing launch to perform these vitally important functions with maximum speed and efficiency.
