Well, it was 15 feet off the ground at the last radar altitude measurement, so that don't leave a lot left to go. At Dulles the at the gate radar alt is -6.

Sorry Turbo, but PA is highly inaccurate. Radio altimeter readings are used for landing and there are 11 other flights in the FDR to assess the reliability of that system. It works great! There is absolutely no indication in the positional, radio altimeter, or acceleratometer readings to support either a NoC or fly-over.
Now some may wish to hold to that theory anyways, but at least be honest enough not to attempt to use the FDR to support it, because it does not.

Highly inaccurate?
Care to quantify your assumption John? How inaccurate are they?
Maybe you can check the FAA requirements and manufacturer spec for
these so called, "HIGHLY INACCURATE" pressure altimeters.

Answer the question John. What is the tolerance +/- at, or below 1000 feet for a commercial category Pressure Altimeter?
I've already done the research and I'll be sure to link everyone here
if you don't...because we really can't continue this discussion based
on your assumptions.
