URGENT UPDATE: The U.S. Air Force has officially launched a series of test flights for the groundbreaking F-15 Eagle at the Grand Forks Air Force Base today, January 5, 1975. This initiative aims to shatter a total of eight world time-to-climb records previously held by U.S. Phantoms and Soviet Foxbats.
Today’s flights mark a pivotal moment in aviation history as the F-15, the first U.S. fighter with a thrust-to-weight ratio exceeding one-to-one, prepares for its record-breaking attempts. The aircraft is uniquely positioned to “launch” like a rocket, capitalizing on the extreme cold of Grand Forks, which significantly enhances engine performance.
During this morning’s session, Maj. David W. Peterson piloted the $7.5 million aircraft on an “area orientation and familiarization flight.” Following him, Maj. W. R. (Mac) Macfarlane took to the skies in the afternoon. While no official records were set today, initial reports confirm that the F-15 exceeded crucial altitudes in less time than required to establish records in multiple categories, including 6, 9, and 12 thousand meters.
The F-15 is designed for high maneuverability in air-to-air combat, and today’s test flights represent the 47th and 48th missions in the ongoing evaluation program that began back in July 1972. Base officials highlighted that with the ideal temperature hovering around 18 degrees Fahrenheit, conditions are approaching optimal for achieving maximum performance.
In a bold statement, Macfarlane described the F-15’s performance as “highly maneuverable,” drawing a vivid comparison: “It’s like comparing an exotic fuel dragster to the family sedan.” This aircraft’s impressive capabilities are particularly evident in its vertical ascent potential, with pilots preparing to push the F-15 to unprecedented heights of nearly 100,000 feet—almost 20 miles above sea level.
The advanced twin-engine fighter has now implemented a hold-back device that permits its engines to operate at full power without brake application, allowing for a rapid acceleration from the runway. During today’s flight, the Eagle soared to approximately 75 feet before executing a steep climb at a thrilling 60-degree angle.
As the F-15 glided effortlessly against the backdrop of a clear blue sky, the pilots were impressed by its performance and agility. The aircraft’s ascent left a striking vapor trail, captivating onlookers and demonstrating the aircraft’s potential for future record-breaking endeavors.
The time-to-climb tests are set to confirm the U.S. holds records for altitudes of 3, 6, 9, 12, and 15 thousand meters, while the Soviet Union currently holds records for higher altitudes of 20, 25, and 30 thousand meters. “We’re testing the airplane handling at high altitudes and low airspeeds,” said Maj. Roger J. Smith, one of the F-15 test pilots.
The excitement surrounding the F-15’s capabilities is palpable, with observers eagerly anticipating its upcoming record attempts. As this story develops, the aviation community—and the world—will be watching closely to see if the Eagle can soar into the history books.
