Yep, a lot of 777s are now grounded after the incident. Japan Air, ANA and United all operations with the 777 planes with the Pratt & Whitney 4000-112 engines.
Update: Now there’s a controversial situation with the PW engines. This week, several planes with these engines had to make an emergency landing.
US plane manufacturer Boeing has recommended grounding all of the 777-model aircraft which have the same type of engine that suffered failure and shed debris over Denver on Saturday. BBC News.
Hope that Boeing can solve this issue soon.
