Upset before take-off by a man boarding a Boeing 737

The incident took place at a Las Vegas airport, with police arresting the man, who eventually fell from the wing and was injured.

Flight 1367, bound for Portland, was about to take off when the pilot spotted a man heading for the aircraft and immediately informed the Control Tower.

The man, who somehow managed to jump over the perimeter fence of the airport, was arrested by the Las Vegas Metropolitan Police and the airport staff.

In the video, taken by a passenger, he appears to be walking on the wing and then heading towards its edge. When he got there he took off his shoes and socks and tried to climb on the winglet of the aircraft. Moments later, however, he appears to slip and fall on the runway.

Alaska Airlines Boeing 737 returned to the gate for inspection and finally took off with a delay of two hours and 18 minutes.
