I don't think there is anything unprofessional in peoples disbelief that following an( on the face of it ) inexplicable accident, heels appear to be getting dragged with respect to getting the recorders to somewhere that someone can glean some info from them. Unlikely I know/hope ,but imagine another one had a related problem in the interim.
While Rome burns Nero fiddles.
As I said, there are lots of these things in the air, incidentally the 777 rollback problem deserves the same sense of urgency, again, some answers are really needed.
