[\u2018On This Day in Space\u2019 Video Series on Space.com]The X-15 rocket plane was part of a series of experimental hypersonic aircraft. This flight marked the beginning of almost a decade of research that explored the altitudes and hypersonic speed at the edge of space. At maximum speed, the X-15 would fly at Mach 6.7 \u2015 4,520 miles per hour! The X-15 program had a total of 12 test pilots, including Neil Armstrong, between 1959 and 1968, making 199 flights in the process. The aircraft flew over a period of almost 10 years. And with a max altitude of 67 miles, it was even able to reach the edge of outer space in the 1960s.","author_name":"Space.com","author_url":"https:\/\/www.dailymotion.com\/space","width":480,"height":269,"html":"<iframe frameborder=\"0\" width=\"480\" height=\"269\" src=\"https:\/\/geo.dailymotion.com\/player.html?video=xae1pna&\" allowfullscreen allow=\"autoplay; fullscreen; picture-in-picture; web-share\"><\/iframe>","thumbnail_url":"https:\/\/s2.dmcdn.net\/v\/bScuM1gIizrqspGWh\/x240","thumbnail_width":426,"thumbnail_height":240}
