Foil 1.2 is the last version of Gregory Payne's airfoil plotting
program for the Macintosh. Foil 1.2 plots high resolution airfoils
from text files, allows section comparisons, and can create coordinate
tables from scanned airfoil images. (Foil 1.2 is free but not public
domain.) If you are downloading Foil 1.2 from the above link, you will
be getting the entire Foil 1.2 file which includes a large collection
of airfoils and a test image for software scanning.
