antonov 225

nice flying!, the 225 is one of my favourite looking aircraft, not the prettiest, that would be concorde, but still wonderful

But, I mean, so what? The truth is everybody copies everybody else to some extent from time to time. It's never smart to ignore a good idea simply because it occurred first in another person's brain. What matters is that, through the collective efforts of all great aircraft design teams, the general cause of aviation was and is advanced.

Manhattan project (atomic bomb) was made in USA... by using german researches and german scientists, so lucky intercepted from the soviets at the end of war

I told you that there are universal engineering solutions -
space shuttle / Buran
Tu 160 / B 1
Bike = Bike (wherever it was made)

I was meaning your stressing on Russian incompetence.
And you're (US) stealing...you stealing minds, that's more dishonorable than copying.

Of cause, especialy Su 27's family and Mig 29's family...You don't know the subject as well as you're trying to perform

Yeah, well that theory might hold up in some cases. But look up a few of the Russian aircraft I've mentioned and you'll see that it's pretty obvious that the designed are copied versions of American designs.

No, see you're confusing this here. Sikorsky chose to emigrate to the U.S. and just happened to design a helicopter. The U.S. didn't steal anything from the Germans. Ever heard of the Manhattan project? I'm talking about items that are designed and built by a country that Russia has directly copied. Why don't we talk about the Rolls-Royce Nene engine? Designed and built by the British and copied by the Russians.

About copying of design ask сhinees .
They know better about it.

and what about the "american" helicopters or helicopter as it is?
It was invented by Sikorsky
(russian emigrant ), maybe you want a fairy tale about an "american" atomic bomb (invented by germans)?
There are universal engineering solution, as you might be know
