Hey kids, welcome back to the Lessin Boy Podcast. Today's story is about the biggest airplane that has ever flown -- a plane so enormous it needed six engines just to get off the ground, could carry things no other airplane on Earth could lift, and had a name that means "dream" in the Ukrainian language. This is the story of the Antonov An-225, nicknamed Mriya -- and it's a story with an amazing beginning and a very sad ending. Let's dig in.
The story starts with the Soviet Union's space program in the 1980s. The Soviets had built their own version of America's space shuttle, called Buran, and they had a problem: how do you move a giant spacecraft from the factory where it was built to the launch site, hundreds of miles away? NASA solved this by strapping its space shuttle to the back of a modified Boeing 747. The Soviets decided they needed an airplane so big it could carry their shuttle piggyback the same way -- except their shuttle was even heavier. So they went to a team of engineers in Kyiv, Ukraine, called the Antonov Design Bureau, and gave them an almost impossible job: build the largest airplane in the world.
The Antonov engineers didn't start completely from scratch. They took one of their own earlier giant cargo planes, called the An-124, and basically supersized it -- stretched the body longer, widened the wings, and bolted on two extra engines, for six engines total instead of four. The result, finished in 1988, is still the largest airplane ever built. Its wingspan is wider than a football field is long. It's about as long as a 25-story building is tall, laid on its side. And when it's working, it can carry up to about 250 tons of cargo -- that's heavier than 40 adult elephants, in one airplane.
They named it Mriya, the Ukrainian word for "dream," because test pilots said flying something that massive, and having it actually lift smoothly off the ground, felt like a dream come true. It has 32 wheels just to hold up its own weight on the runway. It flew successfully, carried the Buran space shuttle on its back a few times just like it was designed to -- and then, almost as fast as it was born, its original job disappeared. The Soviet Union collapsed in 1991, the Buran space shuttle program was cancelled, and suddenly the world's biggest airplane had nothing left to carry. It sat parked in a hangar in Ukraine for years.
But here's the twist: in the 2000s, a cargo airline brought Mriya back to life for an entirely new job -- flying the world's most impossible-to-move cargo. If a company needed to ship something so big or so heavy that no normal plane could carry it, they called Antonov Airlines. Mriya flew giant generators to Japan after a nuclear disaster, rushed medical equipment and masks around the planet during the COVID pandemic in 2020, and set official world records for the heaviest single piece of cargo ever flown on an airplane -- including, in 2001, lifting an entire diesel train locomotive, a record that still stands in the Guinness Book of World Records. There was also something sad hiding behind the whole story the entire time: Antonov had actually started building a second Mriya, a twin sister plane, but it was never finished. Parts of its unfinished body sat gathering dust in a hangar for over thirty years, which meant there was really only ever one complete Mriya flying in the whole world.
On February 24th, 2022 -- the very first day Russia invaded Ukraine -- Mriya was sitting parked at Hostomel Airport, right outside the capital city of Kyiv, undergoing some maintenance work. Russian forces attacked that airport as one of their opening moves of the war, and in the fighting that followed, Mriya was destroyed. The one and only airplane of its kind, the biggest aircraft ever built, a symbol that Ukrainian engineers had pointed to for over thirty years as proof of what their country could build -- gone, on day one of the war.
Ukrainian officials and Antonov have said, more than once since then, that they want to rebuild Mriya using that unfinished second fuselage that had been sitting around for decades -- but everyone involved admits it would likely take years and hundreds of millions of dollars, and it's still not certain it will ever actually happen.
Here's what I want you to remember from this one, kids. Mriya means dream -- and it really was one: engineers looked at an impossible problem, carrying a spacecraft across a country, and built something so audacious that it set world records for decades afterward. But the story also shows you that even the biggest, most impressive things humans build can be fragile, and can be lost in a single day, especially in war. The dream doesn't have to end there, though -- the people who built it once are the same people saying they'll try to build it again. That's the story of the Antonov An-225, Mriya.
