I wonder if by 'firewalling' the thrust levers they severely damaged the engines. I understand it is not (Pinnacle) company policy to 'firewall' but in my experience with pilots from US carriers this is commonly taught. I recall one incident when an aircraft stalled in holding at 20,000 feet. By firewalling they ruined a few of the engines. If there is a possiblity of ground contact - sure. It is all about risk/reward. But at high altitude......
