The rear of the engines is not a lift path.

The BBQ plate only allows for torque and is not a lift path.

I cannot imagine any scenario where a failure of a lift strut, for any reason, would allow the aircraft to continue flying.

You only have to look at the Norn Incident to see the effect of strut failure (for an identified reason)
I WAS going to say "unconnected" reason but, in fact, there is nothing in the public domain to base that on.

I think that we simply cannot imagine the forces acting on the conical housing and airframe once it all goes wrong - torque, gyroscopic, mechanical, aerodynamic, 1500 shp and 6/7 tonnes, 140 knts.

Ugh.
Lynnx,

Thank you.

Very helpful
