An Alaska Airlines flight bound for Los Angeles was forced to return to Seattle, after discovering a ramp agent was trapped in the cargo hold.
Instantly after take off, the pilot of Alaskan Airlines Flight 448 reported hearing banging from underneath the plane.
Seattle television station KIRO 7 reported the worker had taken a nap in the pressurised and temperature-controlled cargo hold, and awoke to find the plane airborne.
The worker appeared to be fine, but was reportedly hospitalised as a precaution.
In a statement, Alaska Airlines said they were actively investigating the matter.
The flight left for Los Angeles 45 minutes after the worker was rescued, this time with only baggage in the hold.
