Sikorsky + Boeing pitch ‘X-2’-based design for US Army JMR TD effort

[IFMU]

I believe Mr. Tischenko didn't challenge the scalability, just the viability of the whole project:

There were some interesting sidelights: the legendary Marat Tischenko, head of Mil under the communist USSR rose to his feet to challenge Finger on making ‘a mistake’ by selecting the co-axial design.

Good comment about pprune vs Wolfram Alpha, I liked that. Also I agree, we will see in time.
