Context: <response>: By 1959, American observers believe say na Soviet Union go be di first to send human go space, because of di time wey dem need to prepare for Mercury first launch. On April 12, 1961, di USSR surprise di world again as dem launch Yuri Gagarin go one orbit around di Earth inside craft wey dem call Vostok 1. Dem call Gagarin di first cosmonaut, wey mean "sailor of di universe" for Russian and Greek. Even though e get ability to take control of im spacecraft manually for emergency by opening envelope wey e get for di cabin wey contain code wey fit be typed into di computer, e fly am for automatic mode as precaution; medical science for dat time no know wetin go happen to human for weightlessness of space. Vostok 1 orbit di Earth for 108 minutes and make reentry over Soviet Union, with Gagarin eject from di spacecraft at 7,000 meters (23,000 ft), and land with parachute. Fédération Aéronautique Internationale (International Federation of Aeronautics) give Gagarin credit for di world first human space flight, even though their rules for aeronautical records at dat time require pilots to take off and land with their craft. For dis reason, Soviet Union no include for their FAI submission di fact say Gagarin no land with im capsule. When FAI filing for Gherman Titov second Vostok flight for August 1961 reveal di ejection landing technique, FAI committee decide to investigate, and conclude say di technological accomplishment of human spaceflight dey for di safe launch, orbiting, and return, instead of di manner of landing, so dem revise their rules accordingly, keep Gagarin and Titov records intact.
