CAIRO -- The Russian owners of the Airbus jetliner that broke up in the air before crashing Saturday in Egypt, killing all 224 people aboard, claimed Monday morning that the crew reported no problems during the flight, and the cause of the tragedy "could only have been a mechanical impact on the plane."
But the Reuters news agency quoted an Egyptian official on the committee investigating the crash as saying a preliminary examination of the plane's flight recorders, or "black boxes," suggested no external object hit the aircraft.
