Hmmm...
Now we see this aircraft in an aggressive side slip, a "duck walk", and a demonstration of "flying on the prop".
This in an aircraft limited to 45 degrees of bank.
I think from the crash video that the reason this flight ended badly is because it remained in the "maneuver" too long....
The example of a successful maneuver completion also showed the aircraft exceeding limits.
Pushing certified limits is not acceptable. It sets a poor example, and should be discouraged. It is so sad the pilots died. It also was not necessary...
"Only in.....anywhere".
