Why The World’s Largest Plane Had a Twin Tail The world’s largest airplane, the Antonov An-225 Mriya, wasn’t just built big – it was built with a revolutionary twin tail design that solved one of aerospace engineering’s most challenging problems. While most people marvel at its massive 88.4-meter wingspan and six engines, the real engineering genius lies in those two vertical stabilizers at the back, a solution that emerged from the Soviet Union’s desperate need to transport the Buran space shuttle across vast distances. This isn’t just a story about building the biggest plane ever – it’s about how the same aerodynamic challenge that stumped Soviet engineers also haunted NASA decades later. When the Soviet government tasked Antonov with creating an aircraft capable of carrying over 231,000 kilograms of payload in 1984, chief designer Viktor Tolmachev and his team faced an unprecedented e
