Relatives react at the scene where the Ethiopian Airlines Boeing 737 Max 8 crashed shortly after takeoff on Sunday killing all 157 on board, near Bishoftu, south of Addis Ababa, in Ethiopia Wednesday, March 13, 2019. The black box from the Boeing jet that crashed will be sent overseas for analysis but no country has been chosen yet, an Ethiopian Airlines spokesman said Wednesday, as much of the world grounded or barred the plane model and grieving families arrived at the disaster site.

Much of the world, including the entire European Union, has grounded the Boeing jetliner involved in the Ethiopian Airlines crash or banned it from their airspace, leaving the United States as one of the few remaining operators of the plane involved in two deadly accidents in just five months.
