A widespread search was commenced including searching and dragging the bottom of Lake Michigan with sonars and trawlers but to no avail.
The day next the crash, the Coast Guard found an oil slick 18 miles NNW of Benton Harbor.
Body parts of some of the occupants washed ashore near "South Beach in South Haven, prompting officials there to close the beach for several days after the disappearance.
However, aside from some light debris found on the surface, little trace of the plane was ever found.
Annually, the search is resuming by the Michigan Shipwreck Research Associates, which is funded by author Clive Cussler.
