Passenger phone found on ground after Alaska Airlines emergency

NTSB investigators arrived in Portland, Oregon, on Saturday to begin their investigation into what happened on Alaska Flight 1282.

As Sean Bates went for a Sunday walk in Oregon, he was keeping an eye out for the door plug from Alaska Airlines flight 1282.

The National Transportation Safety Board had asked the public for help locating the plug, which fell out of the Boeing 737 Max 9 moments after it took off from Portland International Airport on Friday night.

Bates had been scanning for the plug or other debris and as he walked along Barnes Road in Portland. But instead of the door plug, he found something that belonged to a passenger, he said.

"I found a phone sitting on the side of the road that had apparently fallen 16,000 feet," Bates said in a video recorded for social media Sunday.
