Investigators probing what caused a passenger plane to crash Saturday in Egypt's Sinai Peninsula have turned their attention to who was on board — and who would have had access to the doomed jetliner before takeoff, NBC News reported.
An airport source told NBC News that Egyptian security at Sharm el-Sheikh Airport has been focusing on who gained entry to the departure hall, was part of the catering and cleaning services, and had permission to be in the departure lounge.
The Metrojet-operated Airbus A321, which was headed for St. Petersburg, was carrying 224 people on board, mostly Russian vacationers visiting the Red Sea resort. No one survived.
