During one of its early flights when the Su-27 was chasing down the F-15’s world records, the fighter had to start at full power from a dead stop. To achieve this Su-27 was tied to a tank with a cable.

I wonder if the F-15's record that they were chasing down was also set with the F-15 tied to a tank, or was it from a rolling start?

Of more practical interest, what was the remaining range of each fighter after the record stunt? Empty tanks are not of much use, Russian or USA.

From "brake release", whatever that might have been. From The Museum of the U. S. Air Force:

The museum's single-seat F15A, nicknamed "Streak Eagle," broke eight time-to-climb world records between Jan. 16 and Feb. 1, 1975. In setting the last of the eight records, it reached an altitude of 98,425 feet just 3 minutes, 27.8 seconds from brake release at takeoff and "coasted" to nearly 103,000 feet before descending.

Chained to the ground, released by exploding bolts, as I recall the story.
