Air Force One is the official air traffic control call sign for a United States Air Force aircraft carrying the President of the United States .  In common parlance the term describes those Air Force aircraft designed, built, and used to transport the president. The presidential aircraft is a prominent symbol of the American presidency and its power. 
The idea of designating specific military aircraft to transport the President arose in 1943, when officials of the United States Army Air Forces , the predecessor to the U.S. Air Force, became concerned over the reliance on commercial airlines to transport the president. A C-87 Liberator Express was reconfigured for use as a presidential transport, but the Secret Service rejected it because of its safety record. A C-54 Skymaster was then converted for presidential use; this aircraft, dubbed the Sacred Cow , carried President Franklin D. Roosevelt to the Yalta Conference in February 1945 and was subsequently used for another two years by President Harry S. Truman .
The "Air Force One" call sign was created after a 1953 incident during which a Lockheed Constellation named Columbine II , carrying President Dwight D. Eisenhower , entered the same airspace as a commercial airline flight using the same flight number .   
The Nigerian Air Force (NAF) is the air arm of the Nigerian Armed Forces . It is one of the largest in Africa, consisting of about 10,000 personnel  and aircraft including 12 Chinese Chengdu F-7s , and 11 Dassault-Dornier Alpha Jets , 12 Embraer EMB 314 Super Tucano , armed helicopters, and military transport aircraft.
Although an Air Force was originally proposed in 1958, many lawmakers preferred to rely on the United Kingdom for air defence. But during peacekeeping operations in Congo and Tanganyika , the Nigerian Army had no air transport of its own, and so in 1962 the government began to recruit cadets for pilot training in various foreign countries, with the first ten being taught by the Egyptian Air Force .
In July 1971 the International Institute for Strategic Studies estimated that Nigeria had 7,000 air force personnel and 32 combat aircraft: six Ilyushin Il-28 medium bombers, eight MiG-17s, eight Aero L-29 Delfín jet trainers, and 10 P-149D trainers.  Other aircraft included six C-47s, 20 Do-27/28s, and eight Westland Whirlwind and Alouette II helicopters.

The Mikoyan-Gurevich MiG-21 Lancer crashed at around 1:30pm local time on Saturday, around 10km (6.2 miles) north of Fetesti Airbase in Calarasi County, Romania, Cotidianul.ro reported , citing a Defense Ministry statement. The crash killed the pilot, 36-year-old Lieutenant-Commander Florin Rotaru.
Witnesses told local television that the pilot may have chosen to crash in a nearby field as a way to avoid hitting crowds. Around 4,000 people were present at the air show, according to Reuters.
Following the crash, Defense Minister Mihai Fifor told Romania TV that the Romanian Air Force’s planes were all in “perfect working order,” and it was too early to speculate on the cause of the incident. However, Cotidanul.ro reported that 24 MiG aircraft have crashed since 1994. The cause of the crash is currently under investigation.
