In this thread, would posters consider being a little more forthcoming and informative in your posting? If there's something you'd like to say about the conservation of momentum as it relates to the crash and explosion video information, why not just do so and add to the substance of the thread? Once again, I see no reason why PLANE SPOTTERS and NO PLANERS cannot discuss the video data, as data. You know my position, I know yours. No one is trying to change anyone's mind here, I don't imagine. Rather, let's assess the data. What say you?
