URGENT UPDATE: The U.S. Air Force has launched a groundbreaking series of test flights today, January 5, 1975, at Grand Forks Air Force Base, aiming to shatter world time-to-climb records with the advanced F-15 “Streak Eagle”. This high-stakes endeavor could see the F-15, a revolutionary fighter jet, claim multiple records previously held by both U.S. and Soviet aircraft.
The mission commenced with a familiarization flight conducted by Maj. David W. Peterson this morning, followed by a test run from Maj. W. R. (Mac) Macfarlane in the afternoon. Although no official record attempts were made today, preliminary results indicate that both pilots exceeded previous altitudes in significantly less time than required for record-setting attempts in three altitude categories (6, 9, and 12 thousand meters).
The F-15, valued at $7.5 million, is the first U.S. fighter jet with a thrust-to-weight ratio greater than one-to-one, enabling it to “launch” like a rocket, making it uniquely positioned for these record attempts. The strategic choice of Grand Forks for the test flights is due to the region’s extreme cold, which enhances engine performance, allowing the jet to reach altitudes of 100,000 feet in record-breaking time.
Today’s flights mark a pivotal moment in aviation history, as the Air Force prepares to attempt breaking a total of eight world records, including five held by U.S. Phantoms and three by Soviet Foxbats. Maj. Roger J. Smith, one of the test pilots from Edwards Air Force Base, emphasized the significance of these tests, stating, “We’re testing the airplane handling at high altitudes and low airspeeds.”
During the test flights, the F-15 used a new hold-back device designed to allow its engines to operate at full power without needing brakes, leading to faster acceleration. The Eagle achieved a speed of approximately 130 mph before becoming airborne, climbing at a remarkable angle of 60 degrees. This ascent was so striking that it was described by pilot Peterson as a “launch,” reminiscent of rocket missions.
The Eagle’s performance today was visually stunning, with its silver nose soaring against a clear blue sky, leaving behind a lingering white vapor trail. The mission’s success is not just a technical feat; it showcases American ingenuity and the relentless pursuit of excellence in military aviation.
Looking ahead, the upcoming week will be crucial as the Air Force gears up for the official record attempts. The F-15 is expected to reach impressive altitudes, pushing the boundaries of aviation technology and performance. With temperatures hovering around 18 degrees, ideal conditions for the F-15’s operation will further enhance its capabilities.
As the world watches, the stakes are high, and the excitement palpable. The implications of these test flights extend beyond mere records; they symbolize a new era in air combat and technological advancement. Stay tuned for updates as the F-15 prepares to take flight in its quest for aviation glory.
