Many questions lingered Friday about what caused a plane en route to Egypt to fall from the sky. Here's a look back at that story and the week's other top news — in the form of five charts:
1. EgyptAir Jet From Paris to Cairo Crashes With 66 On Board
EgyptAir Flight MS804 en route from Paris to Cairo disappeared Thursday with 66 people on board. Egypt's military said Friday it found the first pieces of a missing EgyptAir passenger plane — though there were no signs officials were any closer to solving the puzzle of what sent the aircraft falling out of the sky. A body part and suitcases were recovered about 180 miles north of the Egyptian city of Alexandria, according to Greek Defense Minister Panos Kammenos. EgyptAir — which sowed confusion after prematurely saying debris was found Thursday — has expressed "deep sorrow for the accident" and offered "condolences to the families of the victims."
2. An American ISIS Cell: The Story of 3 U.S. Recruits
Through documents provided to NBC News by an ISIS defector, NBC News has identified at least 15 U.S. citizens or residents who went overseas and joined the terror group. Some were already known as recruits; other names have never been made public before. Over the course of two months, NBC News pieced together the story of a single cell with three members.
3. Eric Fanning, First Openly Gay Army Secretary, Confirmed
Eric Fanning was sworn in Wednesday as secretary of the Army, becoming the first openly gay leader of any U.S. military service. His swearing in marked another historic moment both for the Obama administration, which has pushed for various gay and lesbian rights, and the groups that have long awaited such a moment. The move comes five years after the repeal of "Don't Ask, Don't Tell," which had prohibited gay and lesbian service members from being open about their sexuality.
4. Sanders Wins Oregon, but Clinton Keeps Her Advantage
Bernie Sanders won the Oregon primary and came very close to Hillary Clinton in Kentucky's contest. His campaign is "willing to do some harm" to Clinton to try to win California next month, the New York Times writes. And they're hoping to take their fight all of the way to July's Democratic convention in Philadelphia. But here's the one little problem with that strategy: The Clinton-vs.-Sanders race really isn't that close — certainly not as close as it was in 2008 between Barack Obama and Clinton.
5. Morley Safer, Veteran CBS News Correspondent, Dies at 84
Morley Safer, the legendary CBS News correspondent who retired last week after more than half a century at the network, died Thursday at his home in Manhattan. He was 84. The death of Safer, who first made his mark covering the Vietnam War and then became one of America's best-known reporters during a 46-year career at "60 Minutes," was announced by CBS on Twitter.
