A float-equipped Kodiak 100 turboprop took off from the Willamette River in Portland on Friday, flying beneath the Hawthorne Bridge as it climbed from the water. Cabel Sasser, co-founder of Portland video game publisher Panic, recorded the departure while walking home across the bridge. He said he initially mistook the distant aircraft for a boat, then began filming because his son is interested in planes. As the plane neared the bridge, Sasser said, he feared he was recording a crash. He watched it pass under the span and continue climbing, then felt relieved when it emerged on the other side. He compared the scene to something from “Indiana Jones.” The aircraft’s tail number identifies it as a Kodiak 100 registered to SNL Aviation LLC, a Seattle-based entity, according to federal records. A representative listed in Washington business records did not respond to a request for comment Saturday. The Federal Aviation Administration was asked about rules that apply to the departure. An agency spokesperson said the FAA would respond next week. Federal rules generally require aircraft, outside takeoffs and landings, to fly high enough that a pilot could make an emergency landing without creating undue danger to people or property below. The regulation does not, by itself, establish whether Friday’s flight complied with applicable rules. Sasser said messages flooded his family group chat after the video spread online. Reactions among viewers appeared divided, he said, between seeing the flight as exciting and considering it dangerous.
