You were quite specific in your original post.
"The MU-2 has the highest accident rate, highest fatal accident rate of any other type of turbo-prop in its class. That's a fact."
Not sure, but I don't think there are any turboprop twin comanches, or B-52s.
If a -6 is an airliner, then I reckon so is the MU-2 and King Air series.
