Egyptian investigators on Saturday issued a final report on a 2004 air crash in the Red Sea resort of Sharm el-Sheikh, saying that technical failures were the main cause for the disaster.
The report also concluded that the pilot suffered from "spatial disorientation" before the air crash, which killed all 148 people on board, most of them were French tourists.
The automatic pilot system had not functioned properly and that the pilot suffered from spatial disorientation, said Shaker Qelada, the chief Egyptian investigator.
The release of the report was delayed from last June because the investigators needed more time to complete their work.
A Boeing 737 crashed into Red Sea minutes after taking from Sharm el-Sheikh airport on Jan. 3, 2004.
The operated charter flight, run by Flash Airlines that has since gone bankrupt, was bound to Cairo for a crew change and then to Paris before crashing into the sea.
The Egyptian Ministry Civil Aviation has since formed an investigation committee to probe the cause of the disaster.
