away, leaving the core engine. The core stage then separated while the rocket was in a suborbital trajectory, and the upper stage carried it to orbit. Once the upper stage finished firing, it separated from the spacecraft, which orbited for 108 minutes before returning to Earth in Kazakhstan. Gagarin became the first human to orbit the Earth. "The feeling of weightlessness was somewhat unfamiliar compared with Earth conditions. Here, you feel as if you were hanging in a horizontal position in straps. You feel as if you are suspended", Gagarin wrote in his post-flight report. He also wrote in his autobiography released the same year that he sang the tune "The Motherland Hears, The Motherland Knows" () during re-entry. Gagarin was recognised as a qualified Military Pilot 1st Class and promoted to the rank of major in a special order given during his flight. At about , Gagarin ejected from the descending capsule as planned and landed using a parachute. There were concerns Gagarin's orbital spaceflight records for duration, altitude and lifted mass would not be recognized by the Fédération Aéronautique Internationale (FAI), the world governing body for setting standards and keeping records in the field, which at the time required that the pilot land with the craft. Gagarin and Soviet officials initially refused to admit that he had not landed with his spacecraft, an omission which became apparent after Titov's flight on Vostok 2 four months later. Gagarin's spaceflight records were nonetheless certified and reaffirmed by the FAI, which revised its rules, and acknowledged that the crucial steps of the safe launch, orbit, and return of the pilot had been accomplished. Gagarin is internationally recognised as the first human in space and first to orbit the Earth. After the Vostok 1 flight Gagarin's flight was a triumph for the Soviet space programme and he became a national hero of the Soviet Union and Eastern Bloc, as well as a worldwide celebrity. Newspapers around the globe published his biography and details of his flight. He was escorted in a long motorcade of high-ranking officials through the streets of Moscow to the Kremlin where, in a lavish ceremony, Nikita Khrushchev awarded him the title Hero of the Soviet Union. Other cities in the Soviet Union also held mass demonstrations, the scale of which were second only to the World War II Victory Parades. Gagarin gained a reputation as an adept public
