I saw it at the Paris airshow, 89. The horizontal stabilizer was big enough to park 4 to 6 F-4s on it. They also had the Buran (Space shuttle) on top of it.
The An-124 is regularly seen in Houston, doing outsized airlift. One or two 225s are flying, and Antonov is thinking of building another, if they can get funding...apparently the outsized cargo business is booming. (Oil-drilling equipment is the primary customer).
