Friday night’s American Airlines Dallas – Buenos Aires hit severe turbulence. I heard that flight attendants hit the ceiling and that they were even hospitalized. I asked American about the flight.
Most of the time severe turbulence comes with warning, either from other aircraft or because it isn’t completely sudden. That means the pilot has the opportunity to turn on the seat belt sign and warn passengers. However severe turbulence does happen without warning. And while it isn’t usually a danger to the aircraft, it’s certainly a danger to passengers.
