Flash Airlines Flight 604 crashes into the Red Sea, resulting in 148 deaths, making it one of the deadliest aviation accidents in Egyptian history.

Flash Airlines Flight 604 was a charter flight from Sharm El Sheikh International Airport in Egypt to Charles de Gaulle International Airport in Paris, France, with a stop-over at Cairo International Airport, provided by Egyptian private charter company Flash Airlines. On 3 January 2004, the Boeing 737-300 that was operating the route crashed into the Red Sea shortly after takeoff from Sharm El Sheikh International Airport, killing all 135 passengers, most of whom were French tourists, and all thirteen crew members. The findings of the crash investigation were controversial, with accident investigators from the different countries involved unable to agree on the cause of the accident.

The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley.

Egypt, officially the Arab Republic of Egypt, is a country spanning the northeast corner of Africa and southwest corner of Asia via the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west; the Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital, largest city, and leading cultural center, while Alexandria is the second-largest city and an important hub of industry and tourism. With over 107 million inhabitants, Egypt is the third-most populous country in Africa and 15th-most populated in the world.
