Actual Cause: Threat Made to the Airplane…

AviationSource approached United Airlines for a comment regarding UA921 from last night.

It turns out it wasn’t a disruptive passenger, but actually a threat made to the airplane.

In the statement, UA said the following on this:

“United flight 921 from London to Newark landed safely in Newark on Monday after a non-credible threat was found written on a lavatory mirror.”

“Our pilots and law enforcement followed the regular procedure for this type of occurrence, which included having customers deplane a short distance from the terminal.”

“The aircraft will receive a security sweep and we’ll get our connecting customers to their destinations soon.”
