Just when you thought it was safe to get back on board of a Boeing 737 MAX airliner again....

The troubled jet, which was grounded for nearly two years after two, separate catastrophic crashes back in 2018 and 2019, was involved in yet another incident this week:  On a flight from Phoenix to Oakland, the 737 MAX 8 started behaving in a wild, almost uncontrollable way while it was cruising at 34,000 feet.

What happened to the plane was called a "Dutch roll."  To explain what is happening to an airplane during a "Dutch roll" KNX chief correspondent Charles Feldman called up aeronautical expert Shawn Pruchnicki at Ohio State.

According to the FAA, the 737 MAX 8 in question sustained "substantial” damage to its tail section as a result of the maneuver, even though it was able to complete the flight.
