Is there a file (other than DAFIF) which has the coordinates of the
boundaries or extents of class B, C, D, E airspace? I can't find anything
in the FAA standard data files. SUA.txt only seems to have things like
MOAs and restricted areas.

Do you have a point, or are you saving it for a special occasion?
