tsmall/JUPTERASC/Zarathu, I have no difficulty with reading and comprehending the English language in its original form. Re-quoting ad nauseam is unnecessary.
Saying that horary questions are invalidated by the following rules:
1. Multiple querents
2. Non-involved parties
3. That this question is of the type that cannot be confirmed
If I am not mistaken, contradicts most horaries you have read as valid.
1. tsmall, when you asked the question about your animals and the court case, was it not possible that the opposition asked that same question, members of your family and their family asked that same question, the judge asked that same question?
Many situations that give rise to horary questions naturally involve several people, Air Malaysia, court case, notwithstanding.
2. Directly or closely involved parties are not a priori qulified to receive answers to all and any question, as many families will confirm. But is it not up to the universe to decide to whom answers are revealed and is it not the hight of hubris to demand that role for yourself on the foreign thread of somebody else?
3. A question of this type stands to be confirmed. For one, the plane could be found. Two, the passengers may be found alive and may self-report.
There are astrologers who would not read an event horary. There are astrologers who do. Despite what your books say, experience/evidence shows that event horaries work.
If you have some knowledge and you want to share it, fine. If you have some knowledge use it to dominate [repeatedly] a foreign thread, fine. But it is an unkind, ill-mannered and ungracious way to behave. The OP confirms.
The horary board is not limited to what you say it should be, neither by rules nor by evidence. People are allowed to use the horary board in asking horary questions open to advancement of theory. I hope in future you may consider this. It has been unpleasant watching this thread taken down through dominiation and ridicule. Other knowledgable astrologers have contributed politely. Peace be with you.
