The Air Force said the plane landed Friday at Peter O. Knight Airport in Tampa, about 10 miles from MacDill Air Force Base, where it was supposed to land, the Tampa Bay Times reported Tuesday.
"I'm quite sure the crew was embarrassed," said Deric Dymerski, president of Atlas Aviation, which runs ground operations at Peter O. Knight Airport.
"They weren't on our frequency. They just showed up," he said. "They obviously, well, I'm speculating, mistook it -- all appearances are they mistook the airport for MacDill Air Force Base."
The Air Mobility Command at Scott Air Force Base in Illinois said the aircraft was en route to the base following Central Command operations in southwest Asia.
Maj. James Bressendorff, AMC public affairs executive officer, said he could not provide details of the mission or the mistaken landing because the investigation is ongoing.
