A tragic accident, but not an act of terrorism - Egypt's verdict on the plane crash in the Red Sea which killed all 148 people on board. French experts are expected in Sharm el-Sheikh today with special equipment to track down the black box flight recorder. Egyptian authorities are adamant there was no explosion on board - they say technical problems could account for the pilot's failure to signal the plane was in trouble. The charter plunged into the sea shortly after take off - it was heading for Cairo to refuel before flying on to Paris. Egyptian foreign minister Ahmed Maher said: "This has nothing to do with terrorism but is related to a technical difficulty on the plane." Rescue workers have recovered several bodies, but the deep waters will make it hard to find the majority of the dead. Efforts have continued overnight. Many of the mainly French passengers were children and included one family of seven. **PHOTO CAPTION*** A rescue team member approaches a piece of debris from the Flash Air passenger plane that crashed in the Red Sea off the coast of the Egyptian resort of Sharm El-Sheikh.
