North American X-15 THE FASTEST X PLANE AND THE FIRST FREE FLIGHT (STANDARD 4:3) RARE DOCUMENT
North American X-15
The North American X-15 was a hyper-sonic rocket-powered aircraft operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's official world record for the highest speed ever recorded by a crewed, powered aircraft, set in October 1967 when William J. Knight flew at Mach 6.70 at 102,100 feet (31,120 m), a speed of 4,520 miles per hour (7,274 km/h; 2,021 m/s), and has remained unbroken as of 2020.
During the X-15 program, 12 pilots flew a combined 199 flights. Of these, 8 pilots flew a combined 13 flights which met the Air Force spaceflight criterion by exceeding the altitude of 50 miles (80 km), thus qualifying these pilots as being astronauts. The Air Force pilots qualified for military astronaut wings immediately, while the civilian pilots were eventually awarded NASA astronaut wings in 2005, 35 years after the last X-15 flight.
North American X-15 (https://en.wikipedia.org/wiki/North_A...)
X-15 Amerika Utara adalah pesawat bertenaga roket hipersonik yang dioperasikan oleh Angkatan Udara Amerika Serikat dan Administrasi Penerbangan dan Antariksa Nasional sebagai bagian dari seri pesawat eksperimental X-pesawat. X-15 menetapkan rekor kecepatan dan ketinggian pada 1960-an, mencapai tepi luar angkasa dan kembali dengan data berharga yang digunakan dalam desain pesawat dan pesawat ruang angkasa. Rekor dunia resmi X-15 untuk kecepatan tertinggi yang pernah dicatat oleh pesawat bertenaga kru, ditetapkan pada Oktober 1967 ketika William J. Knight terbang di Mach 6.70 pada 102.100 kaki (31.120 m), kecepatan 4.520 mil per jam (7.274 km / jam; 2.021 m / s), dan tetap tidak terputus pada tahun 2020.
Selama program X-15, 12 pilot menerbangkan 199 penerbangan gabungan. Dari jumlah tersebut, 8 pilot menerbangkan 13 penerbangan gabungan yang memenuhi kriteria Spaceflight Angkatan Udara dengan melebihi ketinggian 50 mil (80 km), sehingga memenuhi syarat pilot ini sebagai astronot. Pilot Angkatan Udara memenuhi syarat untuk sayap astronot militer segera, sedangkan pilot sipil akhirnya dianugerahi sayap astronot NASA pada 2005, 35 tahun setelah penerbangan X-15 terakhir. [4] [5]
