✈️ #OTD, on October 3, 1968, the first flight of the Tu-154, the most mass-produced Soviet jet passenger plane, took place.

🎛 The airplane was developed in the 1960s in the design bureau of aircraft plant №156. The development was led by Andrei Tupolev.

⚡️ The Tu-154 is one of the fastest mass-produced passenger jetliners, with a cruising speed of over 900 km/h. This performance is ensured by three turbofan engines.

📼 In the 2000s, Tu-154 gradually began to be taken out of service. The reason for that was increased fuel consumption.
