You should get out more...
Gwideman said:Going back to look at Tomfh's post of 18 Mar 18 02:49 (Part I), I see that is shows something different from the animation frames posted on Part IV by INCENTIVE at 24 Mar 18 01:34. I have never been clear whether there are one or two (or more) dashcam videos, so maybe that's part of the difference.
At any rate, here are frames from Tomfh's animation:
The feature circled in frame 1 looked to me like the north west corner of the deck, and I had dismissed it. Not sure why it disappears in frame 4.
But what I only now noticed is the bulge feature circled in frame 4 that enlarges in frame 5, and then appears to blur in frame 6. In the animation, this appears to coordinate with motion of member 11, and seems in line with 11. In short, looks like it could be 11+12 punching out the end of the deck. Too fuzzy to be 100% convincing though, of course.
