A United Airlines passenger’s explosive lavatory episode cancelled their flight, sparked a hazmat response, and became a viral confession.

Nanny and aspiring actress Meghan Reinertsen was flying Lisbon – Newark – Indianapolis when she had an incident she described as “giving birth from the wrong end” that ended with a hazmat crew, canceled flight, and a video that can’t be unseen by the 20 million who’ve watched it.

The trouble started during her connection in Newark. Faint, drenched in sweat, doubled over from cramps, she pushed through customs and boarding without stopping. She made it to her seat, the seatbelt sign still on, and almost immediately realized she wasn’t going to make it. She sprinted to the lavatory — and stayed there for the entire two-hour flight from Newark to Indianapolis.

For the next 20 minutes, I have more diarrhea than any human should have in their life. I’m full-body sweating, I’m crying, my insides are cramping.

By the end, she says every passenger knew it was bad. The pilot expressly allowed her to remain in the lavatory for landing.

Once on the ground, it wasn’t a quick cleanup. There was a full hazmat response, with crews in protective suits treating the cabin. The airline canceled the next flight for a deep clean.

People who claim to have seen the mess in forums and social media paint an even worse picture. One commenter reports there was “doo-doo… FECES!!! … on the WALLS.” It’s unclear if that’s true but the ground reaction suggests the magnitude of the mess may have been that bad.

Of course this is reminiscent of Delta’s now-infamous “brown trail” diarrhea diversion.

How, just how?

A Delta Airlines Airbus A350 turned around back to Atlanta Friday night because of diarrhea throughout the airplane from a passenger and it’s a biohazard.

Reinertsen’s TikTok has been called everything from brave to overshare of the year. She dubbed herself “patient zero” and offered a public apology:

I single-handedly got a flight out of Indianapolis cancelled… If that flight cancellation changed the trajectory of your life in a really negative way, I’m so sorry.

She blames an undercooked burger in Portugal for the incident, but the biohazard reaction suggests a response to the risk of norovirus. After the flight she received a wheelchair escort to baggage claim. But she made it to her evening event in Indianapolis (!), though the nightmare repeated itself at her hotel that night.
