Notwithstanding that this is a rumour network, can I suggest some benefit of the doubt is given in this case until more facts are known?
How do you know that he had not approached this first flight in a thoroughly professional and incremental manner?
How do you know that he got airborne 'inadvertently'?
How do you know that he did not seek advice from professionals?
It certainly does not seem from your post that you know the answers to these questions, so why assume the worst?
I can understand people speculating on the causes of an accident, but I dont see why it is necessary to imply criticism of an individual at such an early stage after the accident.
