Like any major international flight, the plane was packed with passengers from across the world. This one had professors from Kenya, aid workers from Ethiopia, a career ambassador from Nigeria and a fisheries consultant from Britain.

Some were heading to job training, others to an environmental conference. Some were simply going home.

All were passengers on Ethiopian Airlines Flight 302, which crashed on Sunday shortly after takeoff, killing the 157 on board and raising questions about the safety of the aircraft model, the Boeing 737 Max 8.

On Monday, as the identities of more victims were reported, heartache rippled through convention halls, classrooms and living rooms across the globe. Tributes flowed on social media. Colleagues observed moments of silence.
