Sick Passenger Dies Mid-flight After Crew Forgets to Connect Mask to Oxygen Tank

Porscha Tynisha Brown, a 33-year-old civilian employee for the U.S. Department of Defense, died aboard a Korean Air flight from Washington, D.C., to Seoul after suffering a medical emergency mid-flight. But according to a federal lawsuit, her death may have been preventable.

The lawsuit alleges a series of shocking failures by the cabin crew.

About 12 hours into the long-haul flight, Brown suddenly collapsed after telling friends she felt fine just moments earlier. She reportedly clutched her chest and gasped, repeatedly saying, “I can’t breathe.”

Flight attendants rushed over and handed her an oxygen mask — but according to the complaint, it was never connected to an oxygen supply.

Despite wearing the mask, Brown’s condition quickly worsened.

Passengers jumped in to help as the situation spiraled, but the lawsuit claims crew members failed to take control, give instructions, or properly assist.

“At no point did flight personnel take charge,” the complaint alleges, describing a chaotic scene where crew members were “panicking, observing, and taking notes” instead of actively helping.

As Brown lost consciousness, passengers attempted to save her life using onboard medical equipment. An automated defibrillator even issued repeated warnings to deliver a shock — but no one pressed the button.

The lawsuit claims the crew, who were trained to use the device, stood by without acting or guiding others.

With her condition deteriorating, the pilot eventually diverted the plane to Osaka, Japan. Brown was rushed to a hospital, where she was pronounced dead. Her cause of death was listed as acute cardiac failure.

The tragedy has left her family devastated — and raising serious questions.

Brown was described by her attorney as a bright, accomplished young woman with a master’s degree and plans to pursue a doctorate. She had recently been recognized for her work as a safety specialist at Fort Belvoir just days before the trip.

“She was just at the beginning of her life,” her attorney said.

The lawsuit claims that if proper procedures had been followed, Brown may have survived.

It also accuses the airline of failing to act quickly enough, failing to follow emergency protocols, and delaying the decision to divert the flight.

In the aftermath, Brown’s friends were left traumatized — and forced to navigate the difficult process of bringing her body home from a foreign country.

Korean Air has not publicly responded to the allegations.

Now, Brown’s family is seeking justice in court, hoping a jury will hold the airline accountable for what they believe were critical mistakes made in a life-or-death moment.
