Points taken. I understand that the site is fringe, hence I'm seeking more real-world data and trying to do MY OWN reading, since I'm not into strict single-POV assertions. However, in looking at a lot of *different* things one can't help but see the overall patterning in the maner they've described on Thunderbolts. Obviously that's not to say that they "know what they're talking about," however, there are a number o physicists in the group who genreally do try to fact check and proof read before posting TPODs.

And it's precisely the high velocity impacts that worries me about the lack of notable "horizontal" or non-right-angle impacts. Which is whay I'd like to see some and what their characteristics are, to compare with the standard "near-perfect-circle" craters.

Getting back to what I was saying, it's the high-velocity nature of the ipact that worries me. If we're assuming they're at high velocity, can we also assume that the atmosphere and gravity will have a limited impact on their trajectory, considering how high their velocity must be? Conservation of momentum and all that. So, if we assume that they're traveling at "hyper-velocity" and not uber-affected by the atmosphere or gravity of Earth but simply impact due to their overall trajectory and speed. Would we not expect to see more asteroids coming in at shallow angles and scoring long craters along the surface? amusingly, again, I wonder if it's possible for a hyper-velocity impactor to skim through te atmosphere and miss, or more unusually, skim over the surface at a shallow angle and either miss and skip back out of the atmosphere simply due to its overall velocity, or impact shallowly, "bounce" and keep going. Assuming it has the mass and momentum on its side. Or would friction from the atmosphere + gravity dissipate too much forward momentum to allow it to exit the atmosphere again? I realize that this is an out-there question, and asking it as such without expectation of too much weight being put on it, since I don't put much weight behind it. Just wondering if it's possible. And if so, what would happen, would it leave a big 'ol scar on the surface of the planet? Probably a fairly long one? Or if it couldn't escape, would it hyper-skid-to-a-stop? *wink* (again leaving a rather long trail of destruction behind it that's hard to miss? and a large path of ejecta along the surface and or into space ahead of it?)

Just casual musing. But I just wonder about it 'cause I'd somehow doubt that every impact could/would be head-on, right down the middle, unless there's some bizarre force altering the momentum sufficiently to "bulls-eye" the targeting system rather than having it glance of the atmosphere or scorch a path over it, or scar a giant long path...

Again, just a speculative question around why all the impactors seem to be circular and not trenched.
