Well, sorry, please put it down to my being shocked at the irresponsible behaviour of one pilot. I certainly did not want to offend anyone. But I do be aware that in this country it has become virtually impossible - except for the military - to organise any aviation event including aerobatics, following an incident where another pilot killed himself AND several spectators through disrespecting given rules.
On re-perusal, this discussion seems to have slipped into flight preparation, the difficulties of properly consulting published notams, and - for myself - the surprising differences between one country and one other.
The original message was about a pilot who most likely knew very well what was happening then and there - but decided to do his own thing nevertheless. Certainly my instructor would have termed that much worse than "seeming to suffer from an excess of temperament" but I'll not cite his vocabulary - it wouldn't bear translation, anyway.
