Moscow, U.S.S.R: Cosmonauts Pavel I. Belyaev (left) and Alexei Leonov, who last week shot to fame and history-making in their spacecraft Voskhod II, wave bouquets of flowers from their flower-strewn car as they are driven in triumph on the way to Red Square today. Sitting proudly behind them in the car are their wives, Tatyana Belyaeva (left) and Svetlana Leonova. Spaceman Leonov became the first man to "float" in space, tethered only by a thin lifeline to the Voskhod II, commanded by Belyaev. 23 March 1965
