1. Roughly two-thirds of the 737 Max 8 aircraft in the world have been pulled from use with one notable exception: in the United States.

Two days after 157 people were killed on a Boeing 737 Max 8 flight from Ethiopia to Kenya, European Union officials grounded all of the planes traveling in and out of its member countries, following similar moves by aviation regulators in China, Indonesia, Singapore and Australia.

The U.S. Federal Aviation Administration said it would examine the data from the Ethiopia crash but added that it was too early to determine what caused the fatal accident. The agency also cautioned against making comparisons to an October crash in Indonesia involving a Lion Air flight aboard a Max 8.
