About a year ago I speculated that the shadow of the plane might have passed north of the Citgo, which given the speed of the plane and the various view obstructions such as the Citgo canopy, might have caused some of the witness' confusion about the plane's exact path.
At the time, working from the "official" flight path, I ended up concluding that the shadow would still have been too far south to be north of the Citgo, and discarded the hypothesis.
However, since that time I've learned more about the range of uncertainty of the actual path and the altitudes and rates of descent in that region. For instance, the approximately 10 degree bank at impact suggests that the plane was indeed turning slightly to the right, indicating that it came from a slightly more northerly direction in the final few hundred feet. So, the hypothesis that the plane's shadow passed over or slightly north of the Citgo station building turns out to be plausible (though far from proven) after all.
