Aside from his short stature at 5 ft 2 inches, one of Gagarin's most notable traits was his smile. Many commented on how Gagarin's smile gained the attention of many in the crowd on the frequent tours Gagarin did in the months after the Vostok 1 mission success, particularly when he visited Manchester in the United Kingdom. Sergei Korolev, one of the masterminds behind the early years of the Soviet space program later said that Gagarin possessed a smile "that lit up the Cold War".
