The Tupolev Tu-154 is a Soviet-designed, three-engine jet airliner that first flew in 1968. It was primarily used for medium to long-haul flights and became popular among airlines in the Eastern Bloc and beyond. The aircraft is known for its distinctive T-tail and has a capacity to carry around 150 passengers. Over its production run, which lasted until 2013, the Tu-154 was used for both commercial and military purposes. It was praised for its performance in various weather conditions, but it also faced criticism for its noise levels and fuel efficiency compared to modern aircraft.
