The pilot, who was in charge of the safety of the passengers boarded on EgyptAir flight MS804, made a distress call to the control room, claims revealed on Sunday.

Pilot Mohammed Said Shoulkair had a conversation with air traffic controllers in Cairo for “several minutes” before the Airbus A320 crashed. It was previously reported that the pilot lost all radio contact before the flight en route from Paris to Cairo crashed somewhere close to the Mediterranean Sea. The plane had 66 people on board, composed of 56 passengers and 10 crew members. The passengers’ relatives gathered together to mourn the loss of their loved ones when the reports made such claims.

According to the Daily Mail, the pilot called the Cairo control room as he was worried about smoke inside the plane and said that he would be making an emergency landing. A French TV channel, M6, reported that the pilot made some quick measures to put the fire out of the plane and clear the smoke. He conducted a “rapid descent,” which involved a sudden dramatic change in cabin air pressure and was considered a dangerous process.

Prior to the report of the crash, the plane went missing and an EgyptAir spokesman claimed there was distress call made by the pilot to the air traffic control room in Cairo. However, the statement was dismissed by the Egyptian military and the airline itself. French air accident investigation agency BEA sent three investigators to Cairo to take part in the investigation process. No confirmation or comment has been made by authorities on the M6 story.

According to the NY Post, Egyptian President Abdel-Fattah el-Sissi confirmed on Sunday that the investigation will take some time to discover the exact cause of the crash. “This is not one scenario that we can exclusively subscribe to … all scenarios are possible,” he told on Egyptian TV on Sunday.

On the other hand, Greek Defence Minister Pano Kammenos claimed the plane dropped suddenly from 37,000 feet to 15,000 feet and started making “sudden swerves.”
