So, how about a little common sense here? Yes, a low alt fuel dump is an uncommon scenario that is normally unacceptable and merits public concern. However, it could result from a whole spectrum of flight problems, many of which are a normal operating risk in abnormal situations but, some scenario's could include mistakes or inadvertent actions. The investigations will establish the truth of the circumstances. So, little point for posts that say "no reason for" or "you don't have to do that" etc, because there could be. The investigation will show...!
