How about indicating the name of the airline,just so I don't ever have to fly on them.
That sort of an issue,in not at least investigating a possible defect,is criminal.
How did the engineers determine what the problem was?
Even if it was a quality issue and not an airworthinessissue ,I bet the pax were none too impressed with probably most of the dunnies out of action.
Sounds like something an Indonesian airline might contemplate!!!!
