Older 777 aircraft grounded after engine failure

A United Airlines Boeing 777 with Pratt & Whitney 4000 engines dropped engine parts in the Denver area before landing safely.

United Airlines has suspended flights with the Boeing 777 aircraft with the Pratt & Whitney 4000 engines. United Airlines is the only US commercial airline using this type of aircraft. Airlines in Japan and Republic of Korea also use this aircraft; Japan’s regulator has ordered airlines there to suspend flights with this aircraft.

Good. I’m so glad there were no casualties on the ground. (Of course on the plane, too).
