I have very mixed feelings on this. Firstly the fact that he had no medical licence etc had NO relevance to the crash.
IE Had he had all the documentation the accident would still have happened.
Whether his lack of licences indicated a personality type who is more prone to take risks and to do low level aerobatics to impress his passengers is another thing.
We have enough regulations as it is without further prying into our lives and habits. All these regulations do is to equal more expense to the pilot and more hassle and in the end less freedom in our already over stifled point a finger society.
If this accident had been put down to pilot incapaciation due to a heart attack and no medical for several years then yes this thread drift could be justified.
The fact is that it wasnt! The fact is that this accident was caused by someone larking about probably trying to impress his passengers and not within its weight or CofG limits.
The pilot could have had all his documentation in order and the accident would still have occured.
It would be better to stress the fact that aircraft do bite with tragic consequences when abused and that is the real lesson to be learnt from this.
