An Ethiopian Airlines flight traveling from the Ethiopian capital Addis Ababa to Nairobi, Kenya, crashed Sunday morning, killing all 157 passengers and crew on board. The Boeing 737 was carrying passengers of 35 different nationalities, including eight Americans. The U.N. confirmed at least 19 of its staffers were on board the plane. This is the second fatal crash of a Boeing 737 MAX 8 in the past five months, after Indonesian Lion Air Flight 610 crashed last October, killing 189 people. China, Indonesia and Ethiopia announced they were grounding the aircrafts following the crash.
