A rare aviation spectacle drew attention at Budapest’s Ferenc Liszt International Airport on Saturday when an Antonov An-124 Ruslan, one of the world’s largest cargo aircraft, landed in the Hungarian capital.

The enormous Ukrainian-built transport plane arrived from Leipzig, Germany, and quickly became the focus of aviation enthusiasts and plane spotters. Operated by Antonov Airlines, the aircraft was parked away from the airport’s main terminal following its arrival, while speculation mounted about the nature of its cargo.

A flying giant with a legendary reputation

The Antonov An-124 Ruslan is widely regarded as the largest serially produced cargo aircraft currently in operation. Designed during the Soviet era and first flown in the 1980s, the four-engine giant remains one of the most capable heavy-lift transport aircraft ever built.

Depending on configuration, the aircraft can carry well over 120 tonnes of cargo, with some sources citing a maximum payload capacity of around 150 tonnes. Its enormous cargo hold allows it to transport oversized industrial equipment, energy infrastructure components, specialised vehicles and other freight that conventional cargo aircraft cannot accommodate.

Because of these unique capabilities, every appearance of the Ruslan at a commercial airport tends to attract considerable attention.

Mystery surrounds the Budapest cargo

Although the aircraft’s arrival from Leipzig was confirmed, no official information has been released regarding the cargo it transported to Hungary.

The absence of details has fuelled widespread speculation among aviation enthusiasts. Historically, An-124 aircraft have been used for transporting oversized industrial machinery, power-generation equipment, humanitarian supplies and other high-value or unusually large cargo.

For now, however, what exactly arrived aboard the giant aircraft in Budapest remains unknown.

The “little brother” of the legendary Mriya

According to HVG, the An-124 is often referred to as the smaller sibling of the Antonov An-225 Mriya, the legendary six-engine cargo aircraft that held the title of the world’s largest aircraft.

The Mriya was originally developed for the Soviet space programme and later became famous for carrying extraordinary cargo around the world. Tragically, the aircraft was destroyed during Russia’s invasion of Ukraine in February 2022 after being damaged during fighting at Hostomel Airport near Kyiv. The loss of the unique aircraft was mourned by aviation enthusiasts worldwide.

Today, the An-124 remains the largest serially produced cargo aircraft still flying and continues to play a vital role in specialised heavy cargo operations.

A notable day for Budapest Airport

The Ruslan’s arrival was not the only significant aviation event in Budapest on Saturday. The day also marked the return of direct flights between Budapest and Toronto after a multi-year absence.

Air Canada resumed its seasonal service between the two cities, operating Boeing 787-9 Dreamliner aircraft up to five times per week between 6 June and 24 October. The route is expected to offer nearly 48,000 seats during the summer season, strengthening travel links between Hungary and Canada.
