All 157 passengers and crew members aboard the ill-fated ET 302 flight were killed. The plane disappeared from the radar six minutes after leaving the ground. It was the second such fatal crash involving a Boeing 737 MAX 8 model in five months, prompting the grounding of all such aircraft worldwide. /VCG Photo

The mourning relatives are waiting for answers about what exactly happened. The pilot had reported problems shortly after takeoff and was given clearance to return to the airport seconds before the plane went down. The black boxes of the plane have been recovered and are being analyzed in France. Although the cause of the crash has yet to be known, Ethiopian authorities said the similarities between the two crashes were "clear". /VCG Photo

At the funeral, family members carried the portraits of their loved ones. The burial ceremony was also attended by Ethiopian Airlines crew members who lost eight of their colleagues. /VCG Photo

Families of passengers are reportedly being given a one-kilogram bag of earth from the site of the plane crash to bury in place of the remains of their relatives, as pieces of the body parts collected from the scene are undergoing DNA analysis. /VCG Photo
