Basically It is a choice of believing a a bunch of guys on the internet commenting and rehashing comments on a video that was not seen unedited or complete, or a person with ties to the AMA that claims to have spoken first hand with the parties involved. As far as the quotes by the individuals involved, well they are biased parties. Not many people on the internet try to get the full, or real, story and will rant on about what they believe is right or wrong. You just have to find the source that you believe to be most credible and go with it. I will say though if internet forums and Youtube are your only sources then I know a girl in the Mideast that needs help getting her dead parents millions out of the bank, and she will even split it with you. The only thing certain in all of this is a final ruling will be made by the NTSB, FAA, and probably civil court. The odds are not one of these will be 100% accurate.

P.S. As far as the NTSB and news sources, these were just preliminary and will be amended as more facts come to light. To be honest I still take the final NTSB report with a grain of salt.
