Passengers aboard what one woman called the "scariest flight of my life" are breathing sighs of relief after making a safe landing following a midair engine problem.
According to CNN, United Flight 1175 from San Francisco lost an engine cover over the Pacific Ocean less than an hour before it was set to land in Honolulu.
"There was a loud bang ... and then the plane really started shaking," passenger Allison Sudiacal told KHNL. "It was like rattling and the plane was kind of shaking like boom, boom, boom."
Passenger Maria Falaschi tweeted several photos along with the caption, "Scariest flight of my life."
The Boeing 777, which was carrying 363 passengers and 10 crew members, "declared an emergency due to a vibration in the right engine" before safely landing about 40 minutes later in Honolulu, the Federal Aviation Administration said, according to KHON. Emergency personnel were "standing by as a precaution," the Hawaii Department of Transportation said.
"Our pilots followed all necessary protocols to safely land the aircraft," United said in a statement, according to KHON. "The aircraft taxied to the gate and passengers deplaned normally.”
The FAA said it is investigating the incident.
