Looking at the approach plate for RNAV GPS 19L into McConnell, I noticed that the IF/IAF, WITBA, calls for 4000ft MSL and is about 8 miles from and 2600ft AGL above Col Jabara. The airport lines up for almost a perfect 300ft/mile approach to a 6000x100ft runway that is proportionally the same as a 12000x200ft runway (19L is actually 12,000X150, but signage and lighting for 300ft wide). I can see how its possible that they could get sucked in to seeing that field and just breaking off the RNAV approach and landing visually.

The mind is a terrible thing.....
