Just by chance, did anyone keep a copy of the Flight Test article by Dick Johnson (Soaring Magazine) in which he showed the formulas he used to correct his flight test data to sea level conditions? (Or, maybe you just happen to know the month and year of the article?) I've now sorted thru lots of flight test articles on the SSA website but as if yet have not lucked out in finding that one article. Thanks, Darrel


For an alternate take by a master from the same generation, see:

"Gear Up, Sun Up" by Paul Bikle, Soaring July 1970.
