Key Takeaways:

  • An Air Force C-17 Globemaster III mistakenly landed at the Peter O Knight (KTPF) general aviation airport instead of its intended destination, MacDill Air Force Base (KMCF), in Tampa, Florida.
  • The investigation concluded the error was not simple human error, but largely due to crew fatigue and reduced cognitive effectiveness (pilot at 79%, copilot at 89%) caused by multiple mission changes, long flights, and time zone shifts.
  • Contributing factors included both airports sharing the same Runway 4-22 heading, despite KTPF's runway being significantly shorter—only one-third the length of MacDill's—requiring maximum effort braking for a safe stop.

The Air Force has concluded its investigation into an incident last July when a C-17 Globemaster III landed at the wrong airport. And the reasons for the mistake, according to a report that resulted from the Air Force investigation and published by the Tampa Bay Tribune, went beyond simple human error.

Rather than touching down at its intended destination — the MacDill Air Force Base (KMCF) in Tampa, Florida — the large cargo airplane landed at the Peter O Knight (KTPF) general aviation airport. KTPF is located about five miles northeast of KMCF on a similar albeit significantly smaller peninsula. The runway heading would have indicated to the pilots that they were approaching the right airport as both airports have the same Runway 4-22. However, it is surprising that the pilots of the heavy jet didn’t notice the difference in the runway lengths. KTPF’s runway is only about one third of the length of MacDill’s.
