The United States National Transportation Safety Board (NSTB) has said it is investigating a United Airlines flight from Lagos to Washington

Nearly 40 people were injured when a Boeing 787-800 plane suddenly lost altitude during a United Airlines flight from Lagos, Nigeria, to Washington, D.C., early Friday, officials said.

The plane headed back to Nigeria after experiencing "unexpected movement" mid-flight on Friday, Jan. 24, according to multiple reports

In a statement on X, formerly known as Twitter, the NTSB said that it was investigating the January 24 incident involving a United Airlines Boeing 787-8, registered as N27903, which was operating flight UA613 from Lagos Murtala Mohammed Airport (LOS) to Washington Dulles International Airport (IAD).

It is unclear what caused the jolt; United Airlines has said the cause was not severe turbulence, and that it is “working with aviation authorities in the US and Nigeria to understand the cause.”
