It's either that it has not yet taken off, in case one would perhaps expect a note on delayed activities, or it is a failure, and the motivation to inform is not great, atleast not until it is understood what happened.
It could also be that the result is bafflingly monumental , such that one cannot find words at this moment, and more data needed to understand.
Or perhaps it was a nice reproduction, and data is collected over a period, soon to be revealed.
Attach probabilities to the above situations as your own mind see fit.
I trust Brian Ahern will inform us soon of any outcome, whatever it may be.
