Which was an air force officer and an ESA astronaut, Claude Nicollier or Roberto Vittori?
Roberto Vittori Roberto Vittori (born 15 October 1964 in Viterbo) is an Italian air force officer and an ESA astronaut. After graduating from the Italian Accademia Aeronautica in 1989, Vittori flew in the Italian Air Force. He then trained as a test pilot in the United States.
Giovanni Ancillotto "Lieutenant" Giovanni 'Giannino' Ancillotto (15 November 1896 – 18 October 1924) was an Italian World War I flying ace credited with 11 confirmed aerial victories. Rather unusually, he served solely with aviation while he was in the military, beginning in the lowest rank. Among his aerial victories as a fighter pilot were three over enemy observation balloons right after the Battle of Caporetto. As an example of the hazards of balloon busting, on 5 December 1917 Ancillotto returned to base with singed swatches of the third balloon's fabric adhering to his damaged fighter plane.
