The 747-400 burns about 30 tons an hour at brake-release (total; about 15k per engine).

The F-4 burns 50 tons an hour in afterburner, total (98,500 lbs).

The T-38 burns 10 tons an hour in burner.

The Olympus engine was 32,000 lbs of thrust dry, and 38,000 in burner (not much extra, according to Wikipedia) which would make it slightly more efficient than the F-4 or T-38, but I would guess each engine would burn about 30 tons an hour in burner, and about 6-7 tons in cruise.

Maybe he said 140 tons an hour?
