An unauthorized person reportedly took control of a jet Friday evening and took off from Seattle-Tacoma International Airport in Washington state, though authorities have not yet confirmed the reports.
However, around 9:15 p.m. PDT, Alaska Airlines tweeted: "We are aware of an incident involving an unauthorized take-off of a Horizon Air Q400. We believe there are no passengers on board. More information as we learn more."
Early reports indicated the suspect was speaking to air traffic controllers.
The FAA says it cannot confirm any reports at this time.
