I flew thru Omaha, look at KOMA (main airport). There is an airforce base 10 mi south KOFF. Would be easy to mistake the two if you broke out of the clouds south of KOMA.
"Easy" is such a subjective word.
The runway layouts and alignments of Offutt Air Force Base and Omaha Eppley are considerably different, so it would be LESS easy to mistake the two than some of the other AFB/civil field pairs mentioned in this thread.
Offutt has a single runway, Eppley has three.
Offutt's runway is oriented 30/12. Eppley's are 32L/14R, 32R/14L, and 36/18.
Neither airport is located conveniently along or near the path you might take to fly towards the other airport.
In most of the situations cited in this thread and in most incidents, the runway layout is very similar in terms of numbers of runways and the orientation of the runways. To further complicate the scenarios, the "wrong" airport often comes into view while properly aligned for the "right" airport, just at an earlier than normal time.
For example, the Runways at Rapid City are 32/14 and 05/23. Runway 32/14 is large (8,701' x 150') and quite visible, while the perpendicular runway is relatively small (3,601' x 75') and difficult to spot. Ellsworth's single runway 31/13 is very large (13,497' x 300'), is oriented quite similarly to Rapid City's large runway, and is located near the course one might fly to land on Rapid City's Rwy 32.
An
aerial view shows how you might easily confuse the two if you were perhaps lined up for Rwy 32 at Rapid City and popped out of an overcast to see Ellsworth off to the left a little. The situation could be exacerbated if you had a left crosswind and Ellsworth appeared to be straight off your nose. Or perhaps you're on a right base for Rapid City on a somewhat hazy day and you spot Ellsworth as you're turning onto a right dogleg.
In most cases, the landings at the wrong airfields could have been avoided had the pilots used all the resources available to them at the time. However, we're all human, we all tend to love shortcuts, and we all make mistakes. Ergo, this conversation.
