Flying in an airplane is relatively safe. To take it into perspective you are more likely to die in an automobile accident than in an airplane flying thousands of feet above the surface of the earth. This is not to say that flying in an airplane comes without its risks.
Recently Boeing made a statement saying that Airliners who own Boeing 777’s should ground them immediately for an inspection. This came after one of the planes had an engine explode mid-flight. The passengers of the plane said that they heard a loud boom and the plane shook.
They looked out the window and saw that one of the turbines had caught fire. Boeing says that any of their one-hundred and eighty-eight 777’s powered with the Pratt & Whitney engine should be inspected to ensure that the issue doesn’t occur again.
Outside of Denver where the plane took off the plane dropped pieces of the engine in neighborhoods. They were able to turn around and make an emergency landing. While the exact cause of the explosion is unknown both the FAA and Pratt & Whitney engineers are still investigating.
