You can check this out for yourself. The Lat/Long of the
Flight 93 crash site is 40.055 degrees N, 78.901 degrees W, which
converts to 40 degrees 3' 18" N and 78 degrees 54' 4" W. The orientation of the believer to Mecca is the Qibla.
There are several Quibla calculators on the web. Using one of them, and inputting the above coordinates along with local time of 10:06 a.m. EDT, which was the time of impact, the Qibla direction from the impact point to Mecca is 55 degrees 11' 42" (Mecca, BTW, is 10,963 miles away).
