BILLINGS, Mont. — The National Transportation Safety Board has decided to conduct a full investigation of a United Airlines flight from Denver to Billings that hit turbulence over Wyoming, injuring five people.
NTSB public affairs officer Terry Williams says the agency made the decision Wednesday.
The agency has the plane's flight data and voice recorders. Williams says they will also interview crew members and possibly passengers and gather information from the plane to try to determine what happened on Monday's flight and if there are any recommendations that could prevent a recurrence.
Three crew members and two passengers were injured as people were thrown around the plane during the sudden drop. One flight attendant remained hospitalized after Monday night. United spokeswoman Christen David said Thursday the company would no longer give updates on her out of respect for her privacy.
