United Airlines Plane Turns Back After Engine Piece Falls Off.

A United Airlines plane had to turn back to a Connecticut airport after part of the liner from inside the engine's cover fell off. This incident adds to a series of flight mishaps that the airline has experienced this year. The Federal Aviation Administration will be investigating the incident. United Airlines has been under scrutiny for its safety procedures since other incidents, such as a piece of fuselage coming loose in flight and a wheel falling off a plane after takeoff. The plane had 124 passengers and five crew members on board, and it safely taxied to an airport gate after landing. [Extracted from the article]
