I have made no attempt to belittle AM Day whose credentials are well known and whose interpretations of possible / probable / certain chain of events may well be correct.
The whole point is that there are many other "experts", (Sqn Ldr Burke, with his excellent presentation to the HOL committee being one) who interpret those events in a different light.
Hence the doubt, hence the failure to provide the required level of proof
