Las Vegas, Nevada - This is certainly not how passengers imagined their Alaska Airlines flight: just before the plane was about to take off, a man climbed onto one of the wings.

According to USA Today, Alaska Airlines flight 1367 from Las Vegas to Portland was about to take off when passengers were greeted by a strange sight.

The plane was waiting to depart from McCarran International Airport when a man climbed onto one of the wings and walked around for 45 minutes. Eventually, he sat down and started removing his shoes and socks.

Erin Evans, who was on the plane, posted a video of the madness on Twitter: "WTH did I just witness..." wrote the horrified woman.
