Flight and Weather

A pilot was flying a float-equipped airplane along the northern shore of Lake Michigan. During the flight, he observed lowering ceilings and fog over the lake. He provided a pilot report to a Flight Service Station indicating clear air over land. Despite the deteriorating conditions, he continued toward his destination and eventually flew into the worsening weather.

Precautionary Landing

According to the passenger, the pilot decided to make a precautionary landing on the lake due to reduced visibility and low ceiling. The water was rough, and the airplane landed hard. During the landing, the right float dug into the water, causing the aircraft to nose over.

Escape and Rescue Attempt

With assistance from the pilot, the passenger was able to escape the cabin through the passenger window and swim to the surface. She then attempted to help the pilot, who was her husband, but found him stuck halfway out the window. Despite her efforts, she could not free him.
