Details of the ISS are easily found online, as you know.
Big woop, stop wasting time. Do you EVER have anything more than asserting the RE model?
It's not difficult to calculate at all! You get two people at two different points in its path. You measure the time between it being directly overhead for each person. Divide the distance by the time, and woohoo you got yourself a speed.
Would you care to explain how you gain this distance, and how you measure, with minimized error, 'directly overhead?'
I thought NASA only made CGI technology! No known propulsion system could possibly propagate a craft of that size and shape at the speed that it travels. You think that it is more likely that an unknown propagation system flies it through atmosphere than it being in space?
Under the DE model, yes: the question is whether that's more likely than RET. I haven't seen any more than assertion to say otherwise. You don't know the speed, you have given no indication as to the upper bounds of propulsion systems, and yet you're claiming impossibility. That's just assertion.
It's a matter of record that NASA (and related space agencies) have provided and advanced technology. There's no reason to suppose that they're not research organizations, they simply failed at attaining space travel.
