a senior pilot flying for United for more than 25 years, saw the runway directly in front of him. As he was already cleared to land by the Portland tower, Whipple mistook the lights of the Troutdale airport for Portland International Airport and landed on Troutdale's 4,630-foot long runway. No passenger injuries and no aircraft damage was reported. The perplexed, 81 passengers disembarked shortly after their unexpected landing in Troutdale and were transported with their luggage to the Portland airport, approximately 11 miles away. However, deplaning was delayed as passengers and crew waited for boarding stairs to arrive from Portland airport. United Air Lines determined that the DC-8 could take off from the 4,600-foot airstrip in Troutdale, and brought in a pilot, Bartlett Stephens, from Seattle to handle the task. The fuel in the DC-8 was pumped nearly empty, leaving just enough to ferry the aircraft to Portland International Airport, and everything not bolted to the plane was removed. A fence was taken down and some of the grass burned to extend the runway as much as possible for the large jet in preparation for the short flight to Portland airport. The plane was positioned as far back as possible on runway 25, as its tail hung out across Northeast Graham Road. After the aircraft and airport were prepared, pilot Stephens throttled up the jet and started rolling forward at approximately 12:15 pm. The plane took off without incident and rotated a little over halfway down the runway. A few minutes later the DC-8 touched down at Portland International Airport, its intended destination. Following the incident, United Airlines was quoted in the Oregonian newspaper stating the company was conducting an investigation and that Captain Whipple had been grounded pending the outcome. A few days later, Captain Whipple’s license was suspended by the Federal Aviation Administration for 30 days, and also suspended the co-pilot for two weeks. On June 30, 2017, a Robinson R22 helicopter was damaged while performing an emergency landing during training. The pilot lost control of the helicopter's tail rotor as a result of the helicopter slowing down too quickly, the helicopter plummeted to the ground, and rolled over. The aircraft was declared a total loss, but there were no injuries reported.
