Still worthy of a Green Endorsement (Brit Mil thing) for getting it safely on the ground with no injuries but I don't understand why they didn't manually move the ECLs when they realised the beep trims weren't working.
That is a complex emergency that most (including me) would struggle to sort out.
No doubt all the 139 sim instructors out there are working out how to replicate it.......
If that C3 torque tube had burnt through or completely deformed it would have been a much more serious outcome.
