This reopened thead perhaps should contain a reminder of facts.
On the one hand, lots of highly experienced pilots love the T67, have never found it wanting, always responding as expected.
On the other, in the civil arena in the UK, of 80 on the register, 8 have had fatal crashes, 4 of these with instructors on training flights. I understand that this 10% loss is by far the worst of certified aircraft.
Quite apart from the US experience and subsequent scrapping of them, there must be something to be addressed very seriously about them.
