The chairman of Egypt's parliamentary Foreign Relations Committee called on Friday for enhancing cooperation between defense ministries of the countries involved in search of the EgyptAir passenger plane that went missing over the Mediterranean Sea. On Thursday, EgyptAir flight MS804 vanished off the radars. A number of countries, including Greece, France and Egypt, are involved in the search operations. Despite several reports that the EgyptAir plane's wreckage has been found, the airline has said that the investigators are still searching for the remains of the missing plane. "Search of the Egyptian plane is in need of coordination between the states, especially between defense ministries, because there are certain rules that determine the cooperation between the military units involved in search operations," Mohamed Orabi said, as quoted by Al Nahar TV channel. He added that investigations into the incidents with planes demanded extensive resources and could take a long time. The EgyptAir flight MS804 departed from the Charles de Gaulle Airport in Paris, France, at 23:09 GMT on Wednesday. The aircraft was heading for the Cairo International Airport. According to the airline, there were a total of 66 people on board the plane, including 56 passengers.
