It’s in the Russian psyche; their DNA. Much of their stuff is copied from ours, but they put a little artistic flair into their version of the purloined design. Even their weapons are often pleasing in form to look upon. Not exactly a weapon, but their shameless copy of our Space Shuttle had just a few little modifications to the lines of it that made it much more pleasing to the eye. FWIW.
So which of our planes is the Bear a copy of?
