{"product_id":"9781935327868","title":"North American X-15 Pilot's Flight Operating Instructions","description":"North American Aviation's X-15 rocket plane flew at Mach 6.72 and at altitudes above 67 miles -- at the threshold of space. The men who piloted this amazing plane became the USAF's first astronauts. Powered by an XLR-99 engine capable of producing 70,000 pounds of thrust at peak altitude, the X-15 pushed the flight envelope for manned aircraft past the post office. Notably, both Apollo astronaut Neil Armstrong and Space Shuttle commander Joe Engle piloted the\u003cbr\u003eX-15. Originally published by North American for the USAF and later NASA, this \u003cbr\u003eFlight Operating Handbook represents a 1963 update of the original version first printed in 1961. Just recently declassified, it provides a revealing look into one of history's great planes. Also included in this edition is a rare X-15 rescue manual made for the plane's ground crew. Please note: due to the archival nature of some portions of the original documents, image and text quality may vary. Care has been taken to preserve the integrity of the text.","brand":"Periscope Film","offers":[{"title":"Default Title","offer_id":47057849057520,"sku":"9781935327868","price":21.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781935327868_p0.jpg?v=1763656302","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781935327868","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
