Talk:Chetverikov ARK-4

January 2019
THE only REFERENCE ( NOT EVEN sHAVROV) IS A rUSSIAN WEBSITE WITH POOR VERIFIABILITY STANDARDS. Should a verifiable reference emerge there is no reason why the page could not be re-instated--Petebutt (talk) 12:33, 20 January 2019 (UTC)
 * From looking at the specifications, the aircraft looks suspiciously like the ARK-3, particularly the ARK-3-2 second prototype.Nigel Ish (talk) 13:34, 20 January 2019 (UTC)
 * As the three paper sources that the article creator quoted as references do not mention any ARK-4 at all, and the website appears to be vastly short of a reliable source, it appears that the article is a hoax.Nigel Ish (talk) 19:49, 20 January 2019 (UTC)
 * This is not a hoax, per the source that I just added to the article, but it does seem to have been a variant of the ARK-3. Phil Bridger (talk) 19:56, 20 January 2019 (UTC)
 * The source posted appears to say virtually nothing about the so called "ARK-4", literally just a line, and since the authors don't seem to know how many engines the ARK-3 had (it had two) does not seem to be a useful source.Nigel Ish (talk) 20:45, 20 January 2019 (UTC)
 * That may well be true. I'm simply saying that this should not be characterised as a hoax. Phil Bridger (talk) 21:02, 20 January 2019 (UTC)
