Deletion of Beriev Be-2500

Comment: This was redirected twice to a valid topic for this unbuilt project and the most recent time it was restored by a random IP on the basis of . This was not built and never will *be* built so we don't follow the "it's an aircraft, it's notable" standard. It has to clearly pass GNG - and as far as I can tell it does not. There was a brief burst of company-sourced interest in this and then - unlike the OTHERSTUFF the IP cited - it died away to ''nothing''. The references in there now are GlobalSecurity (questionable reliability), Beriev (primary source), and ''Seaplane International'', which is the one that is a start at GNG but.. If anyone can find and add additional ''third-party reliable sources'' that aren't regurgitations of Beriev's promotion at the time, then I'll happily change to Keep - in fact, find one reference in AvLeak and add it and I'll change on the spot - but barring that, this can be covered in the article it has been redirected to, twice
