Last Update to 'Forked Ghosts'

by X.Toff/Tophe, – updated 05/02nd/2014 + 12/22nd/2022 –

'Forked Ghosts' main site
    This is a kind of fourth volume about twin-boom aircraft designs 1939-45 after my books "Forked Ghosts", "Supplement Nr.1 to Forked Ghosts", "The end of Forked Ghosts".
    Writing "The end of" I wanted to stop my endless search, but friends (thanks Max & Paul & Hesham, mainly) have kept on enriching my collection, and I thought I must keep it updated, as a proper way to thank. I posted updates on the What-if Modeller site, but this one requires membership. So I begin presenting them here for direct access.
    As invention is an infinite process, I will not include here the what-if dreams of nowadays using shapes of 1939-45, just the "serious" and "limit" parts of the subject, including dreams made in those years but not anachronic fantasy.

     The chapters will be as in "The end of Forked Ghosts":

Stopping reasons
(2012, July 26th)
I am not an historian, just someone enjoying weird twin-boom aircraft, no matter where they come from. There were 3 faults in transforming that into a collection of 1939-45 true projects (of twin-boom aircraft):
Date issue
When one includes unbuilt projects as well as built machines, the counting of twin-boomers is many thousands of families, impossible to cover all, that is why I focused on 1939-45 (a famous small window). ALAS, this was a trap, and then I was forced to question severely each new revealed project: “what is its design date?”. I hated that severity, that “seriousness” while I am a dreamer.
Copyright issue
At the beginning of the “Forked Ghosts” project, I decided to draw myself each aircraft, but many readers disliked the absence of 3-view drawings (that I used to draw my slanting views). I thought that, for the update, there was no need to spend so much time drawing, I could present the sources, only thumbnails and with links. ALAS this was a trap, and I was forced to wonder severely: “is it legal to show it?”. I hated that severity, that “seriousness” while I was a dreamer. (There is always the risk of a trial for Copyright infringement. Most Historians don’t pay their sources but require to be paid if you are sharing their sources for free. This is so bad a legal context, I feel sick.)
Authenticity issue
When I mixed what-if dreams and true projects (in my book “addition to Forked Ghosts”), I had been condemned by the press and I disliked that. In “the end of Forked Ghosts”, I made separate chapters, and for the Internet update later, I made separate sites. ALAS this was a trap, and then I was forced to question severely each new revealed project: “true or fake?”. I hated that severity, that “seriousness” while I am a dreamer. (I am the author of the book “Escaping Realist dictatorship” and, in my country, my skeptical philosophy is illegal, as it is forbidden to say with the Buddha “all is illusion”, or with Descartes “all might be my dream” – invalidating his mistakes after that step – and the Holocaust is a dogma, whose doubting is punished by one year jail and more than $50,000 penalty; while… doubting of the Amerindian (and Canaan) genocide is legal, this is a racist law, for Israel; I don’t want to be part of this, I give up. I am not anti-Semitic, I am Jewish as Abraham is one of my forefathers, according to my grand-grand-father, who raped the maid. I am less racist than the Bible, the French national anthem, the rabbinical religion. Should I require political asylum in Iran? Alas I am also skeptical towards the Koran…).

Being abnormal, with psychiatric pills everyday, I feel all alone. I stop the part that was pleasant for friends enjoying History, I turn towards the what-if dreamy world. Farewell. (I wrote that explanation for an Arabic friend of mine).
