Sometime in the mid 80's, there was one parked on static display at the annual Oshkosh EAA airshow. It was parked nose to nose to a Lockheed C-5. It was open to walk-throughs to the general public. I recall that while in it, how great a distance it was from the cargo deck to the overhead bulkhead. There was an aluminum ladder that the flight crew climbed up to get to the cockpit. It was a very tall ladder.
A little kid asked one of the Russian crew members a question. He asked, "How high is the ceiling in this airplane" In the Russians very thick accent he replied without a pause, "The ceiling is about ten thousand meters" The kids dad explained to the lad what the comunication error was to his question, about ceiling being how high the aircraft could fly, not how high it was to the overhead bulkhead. The Russian pilot upon hearing that explanation broke out in a big belly laugh, and then answered again, the distance the kid was interested in.
Very big airplane, and yes, it was considerably larger than the C-5
