At about 11:46 a.m. on November 1st, 1949, a 21-year-old air traffic controller at Washington National Airport began calling the same words into his microphone over and over.
Bolivia 927 . . . Bolivia . . . Bolivia . . . turn left . . . turn left . . . Traffic, Eastern DC-4 on final approach and below!
That is the radio transcript TIME magazine published two weeks later. The pilot of the P-38 Lightning fighter never answered. Glen T. Tigner, the controller, switched frequencies and tried the inbound airliner instead.
Turn left! P-38 is traffic!
Eastern Air Lines Flight 537 began the turn. It was already too late.
What Hit What, Half a Mile from the Runway
Flight 537 was a four-engine Douglas DC-4, registration N88727, inbound to National from Boston via LaGuardia. Fifty-one passengers and four crew. The other aircraft was a war-surplus Lockheed P-38L Lightning, registration NX-26927, being acceptance-tested by Bolivia, which had bought it cheap from the U.S. government. Its call sign that morning was “Bolivian 927.”
They collided at about 300 feet of altitude, roughly half a mile southwest of the threshold of Runway 3 at Washington National Airport. The Civil Aeronautics Board would later put the time at 11:46 a.m.
The P-38 was faster. Its left propeller chewed through the DC-4 just forward of the trailing edge of the wing and broke the airliner in two. The forward section sank into the deep water of the Potomac with the crew and most of the passengers. The aft section dropped onto the west bank, near the Richmond, Fredericksburg & Potomac Railroad’s Potomac Yard. Pieces landed on the highway then known as the Mount Vernon Memorial Highway, today’s George Washington Parkway. The P-38 cartwheeled into the river beside the airliner.
All 55 people aboard the DC-4 died. Bridoux, in the P-38, was the only survivor.
It was, at the time, the worst airliner disaster in U.S. history.

“Pieces of Metal Fell Like Paper”
Witnesses watched it happen from the parkway, the rail yard, and the riverbank.
J. Donald Mayor was driving south. He told a reporter for the Evening Star that debris began landing all around his car. He stopped, ran to the shore, and saw a 50-foot section of the airliner half buried in the mud, with six twisted legs sticking out of it.
There was no noise, no groans, or shouts.
PEPCO workers eating lunch nearby looked up in time to see the impact. C.W. Simpson told the Evening Star it looked like “an acetylene torch had just cut the big plane right in half.” His co-worker T.T. Williams waded into the water to help. He pulled people out of the half-submerged tail section and afterwards described what he found.
You couldn’t tell which feet or arms belonged to which people.
Air Force Sergeant Morris J. Flounlacker, on duty across the river at Bolling, jumped in and swam out to the surviving Bridoux. He hauled the Bolivian to shore just as the wounded pilot lost consciousness. At Alexandria Hospital doctors logged a broken back, crushed ribs, and severe contusions. Bridoux soon developed pneumonia. By Boundary Stones’ account, his physicians gave him a 60 percent chance of pulling through.
He pulled through.

Who Was on Flight 537
Most early air travel was expensive enough that the passenger list of any major flight read like a small society page. Flight 537 was no different.
The casualty that hit Capitol Hill hardest was Republican Representative George Joseph Bates of Massachusetts. He was 58 years old, born in Salem, and had served seven terms in the House since 1937. Before that he had been the mayor of Salem for thirteen years. By 1949 he was the first ranking Republican on the House Committee on the District of Columbia, and he had spent enough of his career trying to clean up the District’s finances and push for a measure of self-government that he was widely known as the “Mayor of Washington” as well as the former mayor of Salem.
He was returning from a weekend with his family.
The District lost a friend that morning. The Washington Post obituary line that we quoted in our 2012 version of this post was right on the merits. Bates worked toward congressional approval for home rule. The District would not get it until 1973, when President Richard Nixon signed the Home Rule Act. Bates’ son William Henry Bates won the Salem-area seat his father left vacant and held it for two decades. (And, in a piece of family-tree trivia: George Bates’ great-grandson is the comedian John Mulaney, who has talked about the connection on Late Night with Seth Meyers.)
Helen Elna Hokinson, 56, was on board too. For 24 years she had been one of The New Yorker‘s signature cartoonists, contributing 68 covers and more than 1,800 cartoons. Her recurring subjects, plump society dowagers in cloches and gloves, were known to readers as “the Hokinson Women” or “My Best Girls.” She was on a rare trip out of New York, headed to a Community Chest Drive opening in DC, when the DC-4 went down.
Also among the dead: Michael J. Kennedy, a former U.S. Representative from New York and a fixture of Tammany Hall.
The Washington Post obituary for Bates that ran in the next morning’s edition called the District’s loss “especially tragic.” It was. He was one of the few Republicans on the committee that controlled D.C. who actively wanted the District to govern itself.

Five Minutes of Confusion at the Tower
Bridoux had taken off from National earlier that morning, around 11:37 by TIME‘s account, on what the magazine described as a “practice flight.” He flew north of the Pentagon, circled over Arlington, and turned back toward the airport. He told the tower he was having engine trouble.
The controllers on duty that day testified to the CAB that they cleared the P-38 to enter the left traffic pattern. Instead, they said, Bridoux flew south of the airport and entered a long straight-in approach to Runway 3 from the wrong direction. Flight 537, on a normal short final, was already turning. The P-38, considerably faster than a DC-4 on approach, overtook it.
Tigner’s “Bolivia 927 . . . turn left” calls were going out on the P-38’s frequency. Bridoux did not respond. The CAB report would later note that Bridoux spoke and understood English well, so language was not the explanation.
Bridoux’s own version, when he was finally well enough to give it, contradicted nearly all of that. He told CAB investigators he had taken off from Runway 36, had been in constant radio contact with the tower, and had been explicitly cleared to land on Runway 3 under the call sign “Bolivian 927.” He said the first thing that struck him was a tower voice yelling “Turn left.” A moment later something he did not see hit his airplane.
The CAB heard him out, weighed his testimony against the controllers’ and against a Bolling Air Force Base controller who had been listening in on the same frequency, and discounted Bridoux’s account. One controller, Donovan Davis, broke from his colleagues and corroborated part of Bridoux’s story by testifying that the Bolivian had in fact been cleared to land on Runway 3. The Evening Star ran his testimony on the front page on November 10, 1949.
Eleanor Roosevelt Weighs In
Eleanor Roosevelt devoted her syndicated “My Day” column for November 5, 1949, to the crash. She wrote that it had “made a very deep impression on many people,” and noted that one of the first ideas being floated to prevent it from happening again was to bar noncommercial planes from passenger airports.
That was a real fight. National Airport in 1949 mixed military aircraft with commercial traffic on the same runways. Military takeoffs and landings were a routine part of the day. Within 48 hours of the crash, Eastern Air Lines president Eddie Rickenbacker was on the front page of the Evening Star calling for civil and military traffic to be separated. The same paper ran a piece headlined “Law Sought to Keep Military Planes Off Commercial Airways.”
The CAB’s final report, Docket SA-202, came out September 22, 1950. Probable cause was, in the report’s own language, the “execution of a straight-in final approach by the P-38 pilot without obtaining proper clearance to land and without exercising necessary vigilance.” The board also found that the tower had not warned Flight 537 early enough about the developing conflict. But it added, with some honesty, that even an earlier warning might not have given the DC-4 enough time to break off the turn.
Two weeks after the crash, the CAA told Congress something Washington had been arguing about for years: the region needed a second major airport. The bill that would eventually authorize Dulles had been sitting in committee for months. The death of one of the House’s own people on a runway approach in his own city moved it. We covered the longer story of how Dulles took twelve more years to actually open in our Dulles history post.

The Civil Suit That Reversed the Verdict
The CAB blamed Bridoux. A federal jury, three years later, did not.
Families of the dead sued Bridoux, Eastern Air Lines, and the U.S. government. In January 1953 the case went to trial in U.S. District Court in Washington. The plaintiffs argued that Eastern’s pilots had cut the line for landing without authorization and had failed to keep adequate watch. They argued that Bridoux had only been doing what the tower’s clearance instructed.
On March 14, 1953, the jury came back with the verdict that the Washington Post put on its front page: Eastern Air Lines was at fault. Bridoux was not. The jury allowed that Bridoux could have been more careful, but absolved him of legal blame.
The appellate trail of that decision is dense. The case captioned in Bridoux’s own name, Erick Rios Bridoux v. Eastern Air Lines, Inc., 214 F.2d 207, was decided by the U.S. Court of Appeals for the D.C. Circuit on June 24, 1954. The consolidated families’ suit went up too. Eastern fought it all the way to the U.S. Supreme Court. In 1957 the airline lost there as well.
For a man who had spent four years recovering from a broken back and a broken reputation, and who had reportedly fled Bolivia in 1952 after a coup toppled the government there, the verdict was something close to vindication. He told the Washington Post:
I am convinced now that, in the United States, you find the truth.
Seventy-Six Years Later, Almost the Same Place
On the night of January 29, 2025, an American Eagle regional jet on approach to Runway 33 at Reagan National Airport collided with a U.S. Army Sikorsky UH-60L Black Hawk helicopter over the Potomac. The flight was American Airlines 5342, operated by PSA Airlines, a Bombardier CRJ700 inbound from Wichita. The helicopter was on a routine training run on a published military helicopter route.
Sixty-seven people died. Sixty-four on the airliner, three on the helicopter. The National Transportation Safety Board put the time at 8:48 p.m., the altitude at about 300 feet, and the location at about half a mile from the runway threshold.
In its final report on January 28, 2026, the NTSB pointed at systemic failures in airspace design, in FAA oversight, in the Army’s safety reporting, and in the use of visual separation between commercial traffic and military helicopters around DCA. NTSB chairwoman Jennifer Homendy, announcing the findings, said “the conditions for this tragedy were in place long before the night of Jan. 29.”
She was talking about routes and procedures and chart conventions. She was not talking about 1949. But the parallels are not subtle. Same airport. Same approach corridor. Same altitude band. A military aircraft mixing with a commercial flight on final, in the same half mile of sky where Eastern 537 came apart in 1949.
In 1950 the CAB looked at the wreckage of the DC-4 and said, in essence, that the country had to stop putting fast military aircraft into the same pattern as full passenger airliners on approach. In 2026 the NTSB looked at the wreckage of the CRJ700 and made a version of the same point about helicopters. We told the longer story of the airport’s other catastrophic crash, the January 1982 loss of Air Florida Flight 90, in our post on the icy heroism of that day.
The 1949 crash was one of the reasons Dulles got built. What the 2025 crash is the reason for is being decided now.
