Well, loma, the F-16 was in contact with ATC and on a published approch to Charleston. Whereas, the Cessna was not in contact with anybody, but still looked to be careful, to a point. Looking at that sectional, I would have stayed real low for a few miles before climbing.
Many of us here have flown under "MARSA" rules and such, and many of us have flown at 480, 540 or faster down low on published training routes. The cardinal rule was always look!!!! Our cosmic radar was neat, but an eyeball is worth a thousand mile radar contact!!!!!
