I think what Ghost is getting at Flagrum is that he is questioning the legality of the license of the Bell's IP for the UH-1 because the way BST has stated the copyright info (see below) it sounds like it's from a 3rd party company that Ghost has never heard of and not directly from Bell/Textron. In the manual in the table of contents page, there is a statement of:
"Bell, UH-1H Huey, emblems, logos, and body designs are trademarks of Textron Innovations Inc. and are used under license by Sky Jet International LLC (copyright symbol)"
From what I can find on the net, Skyjet International is a arcade simulator company that does arcade and mobile games and is from Belarus. Founder is Vasily Veka and Alexander Veka. They also founded Altwolf software development. Belsimtek is also from Belarus. So my guess is BST knows them and sub-licensing the IP from Skyjet or BST, Skyjet and Altwolf are all the same people. BST's page has no info about who the owners are.
