doubleu-anker,
As your name suggests, that's a dramatic stance to take on this tragic event.
If you leased your Ferrari to some stranger for 2 years, wouldn't you want to take it for a spin before accepting it back??
I hardly think they would be doing anything out of the ordinary from normal flight envelopes.
Test flights can be for something as simple as checking the pressurisation works to full on stall vane testing. Somethings can't be checked in a simulator, as it might be specific to a particular aircraft.
It's a tragedy, simple. Condolences to those affected....
