On August 31, 1977, Soviet test pilot Alexandr Fedotov zoom-climbed a <a href=\"https:\/\/migflug.com\/aircraft\/mig-25-foxbat\">MiG-25<\/a> to 37,650 metres &mdash; 123,523 feet &mdash; and no air-breathing aircraft has beaten it since.<\/p>\n\n<p>That is more than 23 miles up, well into the black of near-space, where the sky overhead turns dark and the curve of the Earth is unmistakable. The Foxbat got there not by cruising but by trading raw speed for height in a ballistic lunge toward the edge of the atmosphere.<\/p>\n<div style=\"background:#f5f5f5;border-radius:8px;padding:18px 22px;margin:24px 0\"><p style=\"margin:0 0 10px;font-weight:700;color:#333;font-size:15px\">Quick Facts<\/p><ul style=\"margin:0;padding-left:18px;line-height:1.75\"><li><strong>Pilot:<\/strong> Alexandr Fedotov, Mikoyan chief test pilot<\/li><li><strong>Date:<\/strong> August 31, 1977<\/li><li><strong>Aircraft:<\/strong> a specially prepared MiG-25 (designated Ye-266M)<\/li><li><strong>Altitude:<\/strong> 37,650 m (123,523 ft) \u2014 FAI absolute record<\/li><li><strong>Technique:<\/strong> a high-speed \"zoom climb\"<\/li><li><strong>Status:<\/strong> still the absolute altitude record for an air-breathing jet<\/li><\/ul><\/div>\n<h2 style=\"padding-top:22px\">How You Fly to the Edge of Space<\/h2>\n\n<p>No jet can sustain level flight at 37 kilometres &mdash; the air is far too thin for wings or engines to work. So Fedotov did what record-setters do: he accelerated to high supersonic speed in the thick lower atmosphere, then pulled up and let momentum carry the aircraft upward like a thrown stone. Near the top, the engines were starved of air and the controls went mushy, the jet coasting on inertia alone before nosing over and falling back into breathable sky.<\/p>\n\n<h2 style=\"padding-top:22px\">The Plane the West Feared<\/h2>\n\n<p>The MiG-25 was built as a high-speed, high-altitude interceptor, and Western intelligence badly overestimated it &mdash; until a defector handed one over in 1976 and revealed steel construction and vacuum-tube electronics. Yet the Foxbat's brute performance was real, and the altitude record is its enduring proof. Fedotov, a Hero of the Soviet Union, would die in 1984 testing the MiG-25's successor, the <a href=\"https:\/\/migflug.com\/aircraft\/mig-31-foxhound\">MiG-31<\/a>. His record outlived him, and it has outlived every jet built since.<\/p>\n\n<p><em>Sources: F\u00e9d\u00e9ration A\u00e9ronautique Internationale (FAI) record listings; National Museum of the U.S. Air Force; The Aviation Geek Club.<\/em><\/p>\n<!-- mfsh:bottom -->\n\n<button type=\"button\" class=\"mfsh-trigger mfsh-bottom\" data-mfsh-placement=\"bottom\" aria-haspopup=\"dialog\"><svg><use href=\"#mfsh-i-share\"\/><\/svg>Share this story<\/button>\n\n<!-- \/mfsh:bottom -->\n<!-- mf-faq -->\n\n<div class=\"mf-faq-block\"><style>.mf-faq-block{margin:34px 0}.mf-faq-item:not([open]) .mf-faq-answer{display:none !important}.mf-faq-block h2.mf-faq-h{padding-top:22px;margin-bottom:14px}.mf-faq-item{border:1px solid #e2e8f5;border-radius:8px;margin:0 0 10px;background:#fff}.mf-faq-item summary{list-style:none;cursor:pointer;padding:15px 50px 15px 18px;font-weight:600;color:#1a1a1a;position:relative;line-height:1.45;user-select:none}.mf-faq-item summary::-webkit-details-marker{display:none}.mf-faq-item summary::after{content:\"+\";position:absolute;right:18px;top:50%;transform:translateY(-50%);font-size:1.5em;font-weight:400;color:#5C91FF;line-height:1}.mf-faq-item[open] summary::after{content:\"\\2013\"}.mf-faq-item[open] summary{border-bottom:1px solid #eef1f8}.mf-faq-item summary:hover{background:#f5f8ff}.mf-faq-answer{padding:14px 18px;color:#333;line-height:1.6}.mf-faq-answer p{margin:0}<\/style><h2 class=\"mf-faq-h\">Related Questions<\/h2><details class=\"mf-faq-item\"><summary>What is the highest altitude a jet has ever flown?<\/summary><div class=\"mf-faq-answer\"><p>The absolute altitude record for a jet is 37,650 metres (123,523 feet), set on 31 August 1977 by Soviet test pilot Alexandr Fedotov in a specially prepared MiG-25.
