Also, that the B350 crew was able to report it is also suspect. I'm guessing they thought they had right away as they were descending (I'm not a pilot, but someone here definitely had priority I'd assume) but if you can see a plane taking off at you well enough to see the tail hit the ground, surely you should go around?
Seems like the classic 'both parties were in the wrong' situation. Not reporting such a harsh tailstrike does seem rather wild though. Mistakes happen, ignoring them on the other hand is something else.
