The Antonov An-225 Mriya was built to ferry the Russian Buran space shuttle. Buran made only one flight before funding caused its grounding. (Buran was later destroyed in a hangar fire.) Two An-225s were built, but only one was completed. This plane is used to move large cargo and out sized for charter. There were rumors the second An-225 would be completed and made flight worthy, but so far as is known, this has not happened. The sole flying An-225 remains the world’s largest airplane.
Got to see this up close several years ago when it was moving some equipment for Eli Lilly.
Looks great, but it really was a complete pig. Pilot seats mounted on wooden blocks, Dollar Store electric fans mounted on the dash, due to no Air Conditioning, many nearly bald tires showing thread, numerous missing rivets, etc.
The ATA mechanics worked on this thing for free, just to have it in their log books.
Was on the ground here for nearly two weeks, waiting on a part.
