CAIRO: Smoke was detected inside an EgyptAir plane shortly before it plunged into the Mediterranean with 66 people on board, investigators said Saturday, offering clues but no answers as to why it crashed. The Airbus A320 had been flying from Paris to Cairo early Thursday when it plummeted and turned full circle before vanishing from radar screens, without its crew sending a distress signal. Egypt’s military released pictures of wreckage recovered so far, including a pink bag decorated with butterflies, a life vest, shredded seat covers and mangled debris showing the EgyptAir name. France’s aviation safety agency said Flight MS804 had transmitted automated messages indicating smoke in the cabin as the disaster unfolded. While the information may help investigators, more wreckage including the black boxes will need to be found before they can piece together what happened.
