Just wondering about the Osprey aircraft ...
It is impressive, but - My impression is, if one engine/gearbox/rotor pod fails, the aircraft crashes ? I can't see much chance of autogyroing to a landing even if the rotors are working.
Most twin-engine craft have extra safety, these seem to have extra risk. I would re-design it - drive the rotors/pods with electric motors, with two gas turbine generators inboard.. probably cheaper as well.
RIP three brave young lives.

After just such issues early in development a drive shaft connecting the two gearboxes was added. That had its own problems for a while. The above assumes my ageing memory can be trusted.

A stall on one propeller when you are close to the ground doesn't give you much time I wonder if this one was a result of hot air above the deck.
