The Six-Day War begins between Israel and her Arab neighbors Egypt, Jordan, and Syria; Israel has 286 combat aircraft, while Egypt has 430, Syria has 127, and Jordan has 24. Israel opens the war with an 80-minute series of surprise pre-emptive Israeli Air Force strikes against Egyptian Air Force bases which destroy over 250 Egyptian aircraft, almost all of them on the ground, kill some 100 of Egypt's 350 combat pilots, destroy 23 radar and surface-to-air missile sites, and crater the runways of ten major air bases. Egypt is caught with only five aircraft – the Egyptian Air Force's Ilyushin Il-14 (NATO reporting name "Crate") airborne command post and four unarmed trainers – airborne, and the trainers are shot down. Twenty-eight Egyptian MiGs get into the air, but Israeli aircraft shoot 12 of them down and the remainder crash when they cannot find a serviceable runway to land on; the Il-14 lands at Cairo International Airport, the only Egyptian plane to land safely anywhere during the morning. The Egyptian Air Force is knocked out of the war. Israel loses 19 aircraft during the strikes – two Dassault Mystères in air-to-air combat, one Sud Aviation Vautour to ground fire, and 16 to non-combat causes.
In the afternoon, the Israeli Air Force attacks all five Syrian Air Force bases, destroying 51 fighters, two bombers, and two helicopters on the ground, putting all the bases out of service, and shooting down four MiG-17 (NATO reporting name "Fresco") fighters in air-to-air combat. It also attacks airbases in western Iraq, destroying 20 more aircraft there. Israel loses one Mystère. Israel's successful attacks on its opponents allow the Israeli Air Force to focus on ground-attack missions for the remainder of the war.
