Engine Cover Blows Off on United Airlines Flight

“Everyone on our side flung open their windows just to see what the item was,” Ms. Ebert said in a phone interview. “The casing to the engine had sort of flown off. There were pieces flying into the ocean, nuts as well as also bolts flying out a little bit. A bolt hit the wing, as well as also the item just made This specific huge bam.”

Michael Nielson, seated within the middle section of the twin-engine Boeing 777, said flight attendants told passengers to return to their seats immediately as well as also fasten their seatbelts. “The plane shook violently for the better part of a few minutes,” he said in an email. Later, “the shaking subsided to constant, heavy vibration that will stuck around for the rest of the flight.”

Ms. Ebert said the shaking was more intense than she had ever experienced, even on turbulent flights. “Back as well as also forth, down one side as well as also down to the different side,” she said. “The whole thing felt like the item was a roller coaster going to go off the tracks.”

United said in an emailed statement that will the plane, traveling by San Francisco to Honolulu, had made an emergency landing after the engine cowling, or covering, came off. “Our pilots followed all necessary protocols to safely land the aircraft,” the item said. “The aircraft taxied to the gate as well as also passengers deplaned normally.”

As the plane neared the runway, the flight attendants told passengers to brace for impact, hands against the seat in front of them. Some people began sobbing, Mr. Nielson said.

Around 12:40 p.m. local time, the plane touched down — surprisingly smoothly, Ms. Ebert said, as well as also to a round of applause by passengers who had been screaming a few minutes before. Several went on to tweet photos as well as also videos of the damage.

“Scariest flight of my life,” one wrote.

Similar malfunctions have happened before. In 2016, an American Airlines flight by Phoenix to San Francisco turned back after part of the engine cowling fell off. A JetBlue flight by Newark to Fort Lauderdale, Fla., did the same in 2010. as well as also an Air France flight had to make an emergency landing in northern Canada last year after one of its engines exploded in midair.
