UPDATE: The U.S. Air Force has launched a series of urgent test flights today, January 5, 1975, at Grand Forks Air Force Base as part of an ambitious record-breaking campaign for the F-15 “Streak Eagle.” Pilots aim to shatter eight world time-to-climb records currently held by U.S. Phantoms and Soviet Foxbats, marking a significant technological milestone in military aviation.
This morning, Maj. David W. Peterson piloted the state-of-the-art F-15, valued at $7.5 million, during what the Air Force termed an “area orientation and familiarization flight.” Later, Maj. W. R. (Mac) Macfarlane took to the skies, showcasing the aircraft’s remarkable capabilities. Although no official records were set today, Air Force officials confirmed that the F-15 surpassed altitudes faster than required for three altitude categories: 6, 9, and 12 thousand meters.
The F-15, notable for being the first U.S. fighter with a thrust-to-weight ratio exceeding one-to-one, is designed for superior maneuverability in air-to-air combat. The cold weather conditions at Grand Forks—currently 18 degrees Fahrenheit—are optimal, enhancing engine performance to reach altitudes of 100,000 feet in record time.
As the Eagle climbed steeply at a 60-degree angle, it left spectators in awe. “It was startling—as planned,” commented Maj. Joe Higgs, one of the chase pilots. The F-15’s ability to launch like a rocket has drawn comparisons to exotic fuel dragsters, highlighting its cutting-edge technology and performance.
Today’s flights mark a significant phase in a testing program that began in July 1972, aimed at demonstrating the aircraft’s capabilities under extreme conditions. The Air Force is readying for the upcoming record attempts, which will see the F-15 execute time-to-climb tests reaching remarkable heights.
Looking ahead, the base prepares for the official record attempts scheduled for next week. The F-15 is expected to break five records held by U.S. Phantoms and three by Soviet aircraft, setting a new standard in aerial performance.
As the F-15 continues to impress with its agility and speed, the world will be watching closely to see if it can achieve these historic milestones. Stay tuned for updates on this developing story as it unfolds at Grand Forks Air Force Base.
