Yeah, the 3 video frames in that report are matched to transmissions the timestamps. Unless the angle is deceiving, you can sorta visually extrapolate from the descent of the first two at :01 and :04, that 6 seconds later, when the go-around was give at :10, they would have been on the ground had they not pulled up.
o At 2356:04 PDT, ACA759 reappeared on the local controller’s ASDE-X/ASSC display as it passed over the first airplane positioned on taxiway C.
o About 2.5 seconds after advancing the thrust levers, the minimum altitude recorded on the FDR was 59 ft agl.
o At 2356:10 PDT, the local controller directed ACA759 to go around. The airplane had already begun to climb at this point (see figure 4).
This means that if they hadn't acted until they heard from the tower, it would have almost certainly been a disaster.
