:: I am sorry but this issue is laid to rest. It is recorded in an credible document produced by a reputable publishing house. It is verified by two primary sources Admiral William Hall and Major AEW Mason both of NID. The circumstances of the incident are attested by an academic historian. Your hypothesis - "A book my be written that the sky is indeed yellow and we have to accept that all evidence, in this case complete lack thereof, to the contrary?" - is demonstrably false. I am assuming, from your writing style, that English is not your first language, so I have tried to be as clear as possible. Leave this alone.
