From what's available, in the TUAF543 crash, tail separated first. It was found in a location farther from both the wing assembly and the cockpit and it can't be seen on the videos.
The whole ordeal had made me remember that in the past we supposedly were to co-produce the Ukrainian An-70 plane to replace our fleet some years ago. Whatever happened to that? I had completely forgotten about it until this tragic accident.
We need an engine to make our own cargo transporter, tanker and passenger planes. We can wait until after our Kaan engine design work is complete for a focused work but we should start its design work as a side job at once. The world is going towards self sufficiency rather than codependency.
