It's perfectly reasonable to try to find some debris, logical to listen for the recorders' pingers while they work, but why search further, exactly, with hardly a clue to location?
I don't believe for one moment the wrong kind of fire in the wrong place at the wrong time caused this aircraft to "disappear". Therefore I will step aboard certain B777s as usual. Rightly or wrongly.
I don't mind paying tax for RNZAF Orions, usually searching for lost yachties, but if we're going to be paying more for airline tickets the money would be better spent on safety, not satisfying curiosity, however nice that feels.
