Amazingly, the owner didn't realize he'd left his pet snake behind until the plane was on its way back to Anchorage. He alerted the airline officials, who, in turn, alerted the flight staff on the plane.
"The pilot came, and said, 'Guys, we have some loose snake on the plane, but we don't know where it is,"' Anna McConnaughy, a passenger on that Ravn Alaska flight, told the Associated Press.
A search commenced. No one panicked, according to McConnaughy.
Meanwhile, the snake - thought to be an albino ball python - seemed unaware that anyone was looking for him. He was sleeping beneath a passenger's yellow duffel bag.
