20 septembrie: Primul avion de pasageri cu reacție construit în România, ROMBAC 1-11, își lua zborul în fața lui Ceaușescu

September 20 marks significant historical events, including the first flight of the Romanian-built passenger jet ROMBAC 1-11, the earliest mention of Bucharest in 1459, and Magellan's expedition in 1519. Notable births include Romanian poet George Coșbuc and actress Sophia Loren. The day also saw Gandhi's hunger strike in 1932 and the establishment of the Pitești Automobile Plant in 1968, which initiated car production in Romania. Additionally, the evacuation of Romanians from Cadrilater began in 1940 following territorial cessions to Bulgaria.
