The reports go on to state - it is not clear on what basis or where they obtained their information - that the first airfield the crew saw was Tampa Executive which unfortunately they mis-identified as Peter O Knight, and therefore "knew" that the next airfield on track "must be" MacDill.
The trouble with that hypothesis is if you are over Tampa Exec, but think you are over Peter O Knight, then expect to see McDill on the nose you are heading exactly 180 degrees out from what you think you are. Peter O Knight is in the west side of Tampa Bay (a pretty substantial water feature), McDill is on the east side of Tampa Bay at the end of a prominent peninsular, Tampa Exec is landlocked in the junction of 2 major highways. Whatever anyone was doing in that cockpit, it didn't involve any use of a map or a compass.
