Very sad event indeed.
I am sorry I was not going to comment but I am unable to contain myself.
Why, oh why, was a "test Flight" needed?? I take it the aircraft was in airline service on the D (JAA) register. The why did it need another test flight?? What did this flight achieve? Nothing but sadness.
I think it is high time test flying was left to "test pilots" who are current in test flying and nobody else.
It is time playing around or training in aircraft was stopped and done in the simulator.
