No problem, DX, I'm glad to see it sorted out. It is easy enough to misunderstand one-another face to face, much easier on these impersonal web pages. Note to self: next time be more precise, i.e. mention "the joker mentioned originally" or words to that effect.
To continue on the original discussion: how hard would it have been for the organisers to have a Temporary Restricted Zone set up? That would not have changed anything for any pilot not consulting notams of course, but it would have made it possible to dissuade him (her?) from repeating the, err, performance.
Setting up such a TRZ seems rather common in France, at least.
