- Animats 9y agoThey were very close. See [1]. They were over the centerline of taxiway C, and 85 feet AGL crossing taxiway W. Minimum altitude was 2.5 secs later. There were three planes ahead, an A-340, a B-787 (also 55 feet high at the tail), and some UAL jet of about the same size. A few feet lower and there would have been a collision.

- Stratoscope 9y ago"...the minimum altitude recorded on the FDR was 59 feet above ground level." [emphasis added] AGL (elevation above ground level), not MSL (elevation above mean sea level). The runway/taxiway elevation is already taken into account. They were 59 feet above the taxiway.
