Deletion of Pendulum rocket fallacy

Comment: because there doesn't appear to be ''any'' RS we can use to cite this content on ''any'' page. The article begins {{tqq|The pendulum rocket fallacy is a common fundamental misunderstanding of the mechanics of rocket flight}} ... well, how common can it be if we can't even find a reliable source talking about it? Bowery and Manley are self-published sources and there doesn't appear to evidence of their expertise sufficient to satisfy . The other sources are unreliable for reasons explained above. If we had an RS, then I'd say '''merge''', but so long as we don't, it should just be deleted. Otherwise we risk that this is a type of hoax, or at least, there is no support for our stating that this is a "common" fallacy, and we don't need to be covering obscure fallacies that are not covered in reliable secondary sources. Our job is to summarize reliable secondary sources, and here we have none to summarize
