Air Horizon, formerly known as Transtel Togo, was an airline based in Lomé, Togo operating flights within Africa, the Middle East and Asia out of Lomé-Tokoin Airport. The airline was founded in 2004 and shut down in 2007.^[1]

As of March 2007, the Air Horizon fleet included the following aircraft:

• Two Vickers Viscount V.810
• One Boeing 727

• On 24 July 2001, Vickers Viscount 3D-OHM of Transtel was damaged beyond economic repair in a take-off accident at N'Djamena International Airport when the aircraft departed the runway, damaging the engines and propellers.^[2] Although written off by the insurers, the aircraft was repaired. Repairs were almost complete when a soldier accidentally discharged his gun, puncturing a fuel tank.^[3]
