Exactly. Landing a large aircraft is really a math exercise. Horizontal velocity vs vertical velocity versus lift generated/thrust applied. Add cross wind component and density altitude [how thick is the air to produce lift].
With the 777 approach speed of approx 175 mph and a sink rate of, let's say 4000 feet per minute [way to high for short final] calculate how many seconds till impact at the approach angle. Then calculate the engine spool up time from low idle at 20% RPM to full power of 90% RPM... then the time needed to use that full thrust to accelerate a 250,000 lb aircraft. [conservative guess on weight]. Now calculate just how far behind the airplane the crew is ... the human reaction factor.. etc.. If you wait until seconds count, there is never enough time.
