I notice an interesting pattern in the second-by-second analysis shown in earlier posts. The pattern may indicate that the AC pilot(s) may have initiated the go around before the time stamp indicated.
Elevation above ground has already flattened out near 130 feet as the plane overflew UAL1. The next five seconds of data would be consistent with the plane's nose beginning to lift and the tail continuing to drop. For about four seconds there is more tail drop than nose lift, presumably, then the full climb is achieved about two seconds after the indicated marker.
