PORTLAND, Oregon (AP) -- A Nike corporate jet carrying its CEO and six other people developed landing gear problems shortly after takeoff Monday but then made a safe emergency landing after the gear was unstuck.The Gulfstream jet touched down at 12:11 p.m. PT at the airport in Hillsboro, Oregon, the same facility where the plane left, bound for Toronto, around five hours earlier.Nike President and CEO William D. Perez was on the Gulfstream V. He joined the company last year when co-founder Phil Knight stepped down from daily management at the big athletic shoe and apparel company."The pilots -- unbelievable, unbelievable, what they did for us," Perez said afterward. "They were very calm, collected and professional, told us every maneuver they were going to try."The others on board were two other senior executives, a fourth Nike employee and three crew members, the company said.TV footage showed the right main wheel only about one-quarter extended, apparently blocked by the wheel door. The gear was back to normal when the plane finally landed.Allen Kenitzer, an FAA spokesman, said the plane crew took steps to burn off fuel and talked with the Gulfstream company to get advice on freeing the landing gear."The pilot is the ultimate authority in determining what to do with that airplane," Kenitzer said.The airplane made low passes over the Hillsboro runway, briefly touching the runway with the extended left landing gear and then lifting off again, apparently to jostle the other wheel down, said Connie King, spokeswoman for the Hillsboro Fire Department.John O'Meara, a chief test pilot at Gulfstream who helped out from the ground, told MSNBC there was initially some difficulty keeping phone contact with the crew.After that was solved, he said, "in following all the procedures that are already in the flight manual, we were able to talk them through that and ... they were able to get the gear down." The crew, he said, "did a magnificent job."Perez, 58, was named last November 18 to succeed Knight as CEO. He had spent 34 years with S.C. Johnson & Son Inc., the privately held manufacturer of household products.Copyright 2005 The Associated Press.
