Continental TurboProp crash inbound for Buffalo

[Belgique]

Seems clear to me that the answer as to why the aircraft pitched up suddenly, dropped a wing and instantly entered a flat spin is adequately covered here and here

It would appear that not many people are getting their minds around the significance (for spanwise ice distribution) and the resulting very different stall speed/stalling AoA of the left and right wings - caused by both engines' props turning in the same direction.

Think it through people.
