I don't dispute that is indeed what was stated, but the guys in the front had a duty to monitor their 777's performance. They got way too slow and didn't notice it = an error by the pilots! Great if we have a system to help us out and control the airspeed, but your job as an airframe-operator is to: Understand its systems fully; Monitor it!
Way too many accidents when, for whatever reason, the system doesn't do what is expected but the aircrew either don't notice or over-react! Inevitably lessons to be learned about the possible lack of understanding of the automation/monitoring, but you can't absolve the aircrew from not doing what is surely their primary role - flying the aeroplane.
Back on thread, unless the Lamia RJ suffered a totally unexpected and simultaneous loss of thrust on all 4 engines, I can't see how their subsequent reaction was anything other than woefully inadequate. And that's before there is any mention regarding their planning and fuel uplift.
