.. .and do the analysis. Also, someone needs to come up with a rentry scheme involving some kind of invertered titanium-sheet umbrella-like thing that faces earth on the trip back - there really is no way I can think of besides that - re-entry will be like a parking in giant oxy-acetylene torch flame while being tackled by the dallas cowboys for about half a minute. In short, its titanium side down or its a debris field a few miles across with a large glob of smoking thermoplastic in middle.
initial (and reliable) simulations suggested peak velocity will be quite around a mile a second, about twice as fast as a bullet fired from a high powered rifle. nice doppler effect in the audio - as the rocket encounters crosswinds at different altitudes, it may rotate around the horizontal axis in response to wind shear as the center of gravity moves up the rocket body.. and this should be simulated so max safe-launch wind at altitude would be quantified - maybe i'll join up again before then
The original plan had / has a shorter stage one burn than that. It would be a good idea to do a computer sim on changing cross wind horiz. accelerations as the center of gravity of the rocket changes while fuel is consumed. If the rocket is not within 18 degrees of vertical when the 2nd burn is started, it will never reach 'space'. Serious work needs to be done regarding heating of electronics in a vacuum, and also, the trip back is horrendous - the rocket will fall back from - continued

Wait, I just re watched the video.... and the rocket is rotating.

There is a large team of rocketeers researching/working on everything you have described.
This video is an artistic interpretation, don't expect everything to be displayed.

Your simulation neglected to show the rotation of the rocket, which ought to reach 4 turns per second by the time the coast phase is entered.
