The flight
On the night of June 23, 1950, Northwest Orient Airlines Flight 2501 took off from LaGuardia Airport in New York. It was a Douglas DC-4, a propeller-driven airliner, headed for Seattle with a planned stop in Minneapolis.
There were 58 people on board: 55 passengers and a crew of three. The captain was Robert Lind, 35.
Into the storm
The plane’s route took it across Lake Michigan. That night, a severe thunderstorm had developed over the lake. The plane was flying at about 3,500 feet. Late that night, the captain asked air traffic controllers for permission to fly lower. The request was denied.
That was one of the last messages from the plane. After that, it went silent. Flight 2501 never reached Minneapolis.
All 58 people on board were lost. At the time, it was the deadliest commercial airline crash in American history.
The search in 1950
The Navy and the Coast Guard searched the lake. They recovered light debris from the water, but not the plane itself. In the days that followed, debris washed ashore along the Michigan shoreline near South Haven, across the lake from Chicago and northeast of La Porte County.
The main wreckage was never found. Without it, many questions about the crash were never answered. Valerie van Heest, who later wrote a book about the flight called Fatal Crossing, has said she believes a series of errors and bad decisions, together with the storm that night, led to the crash. The original government investigation never settled on a cause.
A twenty-year search
Decades later, a group of volunteers took up the search. Beginning in 2004, the Michigan Shipwreck Research Association, working at first with the adventure author and shipwreck hunter Clive Cussler, went out on the lake year after year with side-scan sonar. Cussler’s backing continued in some form until 2017.
Over about 20 years, the searchers covered at least 600 square miles of lake bottom. They found nine shipwrecks that had never been located before. They did not find Flight 2501.
In 2025, the group ended its search. Searchers believe the plane broke into pieces too small for sonar to pick out, and that those pieces have settled into the soft lake bottom.
Remembering the 58
The search also helped families remember. In 2008, researchers working with the search team found an unmarked grave holding unidentified victims at Riverview Cemetery in St. Joseph, Michigan. A marker was placed there that year in memory of all 58 people on board. It reads “Gone but Never Forgotten.”
In 2015, a second unmarked grave was found at Lakeview Cemetery in South Haven, by the cemetery’s sexton while she was helping with family history research. That June, around the 65th anniversary of the crash, people gathered there for a memorial service, and the name of each person lost was read aloud.
The lake and the legend
Because the plane was never found, Flight 2501 has become part of a modern legend. Some people call a stretch of Lake Michigan between Wisconsin and Michigan the “Lake Michigan Triangle,” and they link the flight to other mysteries there. That is a legend, not a finding. The record points to a summer storm over open water and a plane that was never recovered.
St. Joseph and South Haven are a short drive up the shoreline from La Porte County. For those of us who watch the weather along the Indiana shore, the story is also a reminder of how quickly summer storms can build over the lake. If you stand on the beach in Michigan City on a summer evening and watch clouds tower up over the water, you are looking at the same lake those 58 people crossed.
