Working with ARC's test data, published at Rocketail.com's website, revealed that the added projected frontal area of the 3-wings never made it into the calculations. It appears that ARC simply used the gross frontal area of the Wabash, 53-foot dry van for the 'rig', with no consideration of mirrors, under-airdam clearance, actual wheel exposure, mudflaps, tire gaps, etc., for all the test data, with and without the wings.
