The Antonov An-225 Mriya, once hailed as the grand behemoth of aircraft, was a true feat of engineering. With a staggering length of 275 feet (84 m) and an impressive wingspan of 290 feet (88.4 m), this Soviet-made plane was specifically built to transport the Buran shuttle for the Soviet space program. The Mriya’s exceptional hauling capacity, thanks to its six enormous turbofan engines and colossal wingspan, set a world record in 2001 when it lifted an astounding 253 tonnes into the sky.
