Key Takeaways:

  • An Air Force C-17 Globemaster III mistakenly landed at a small general aviation airport (KTPF) instead of its intended military base (KMCF), despite both having the same runway heading.
  • An Air Force investigation revealed the mislanding was due to factors beyond simple human error, primarily severe crew fatigue and significantly reduced cognitive effectiveness (pilot 79%, copilot 89%).
  • Crew fatigue was attributed to multiple factors, including frequent mission changes, long flights through complex airfields with several stops, and time zone changes in the days leading up to the incident.

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.
