Of course it is in the early stages of the investigation so everything is coming out a little foggy.
Here is what I know:
All three dead belonged to a flying club on the field. The 172 had two people in it, an instructor and a student. I BELIEVE the student was an instrument student and that the aircraft was shooting the VOR r/w 24 into Blue Ash. If this is the case, the student would have been under the hood looking at the instruments and would have no idea an airplane was in the vicinity.
The Beechcraft apparently had departed just previously and was heading North. Apparently Blue Ash was using r/w 6 at the time. The final course for the VOR 24 is almost a straight in aligned with the runway so if an aircraft took off and stayed alligned with the runway they would be almost head on with an aircraft approaching the airport on the instrument app.
It was a clear day, so they SHOULD have seen each other.
That is what I know now more will come later.
