JetBlue Flight 194 was forced to return for Las Vegas McCarran International Airport after the Airbus A320 suffered a loss of two of its hydraulic systems on Sunday.
The pilots determined they needed to turn back and declared an emergency, but first they had to burn off a large amount of fuel. That maneuvering took more than three hours over the desert in turbulence, and reports said a number of the 155 passengers on board became ill. The flight landed safely about four hours after it first took off.
The NTSB is investigating. Listen to audio from the event below.
