Can I suggest we take a break from the meta-discussion and move back on topic? I don't have the tools to decide if Skeptik and Jock are one and the same, but if they are, so what? The hoax claims are either true or they aren't. They aren't.
The point is, can they answer the questions that have been asked of them concerning the Armstrong's Ghost book specifically, and the hoax in general.
As an aside, I have in my 'Saved for later' list at Abebooks a 2nd hand copy of this
DARK MOON : Apollo and the Whistle-Blowers
David S. Percy
Published by Aulis Publishers, 1999
£2.89 - free postage, and not one penny of it goes to David Percy or Aulis.
I still can't bring myself to buy it though. It would pollute my bookshelves.
