Your inability to understand a very straightforward analysis does not suggest that the analysis is hand-waving.
Straight forward my big fat rear end. No pressure on a craft can exists from a wind that you are going at the same speed and direction with. No pressure no force no force no acceleration and no increase velocity over the wind.
Simple newtons' equations a=f/m and v=(A*T^2)/2 +V-old and when force is zero A is zero and you go to constant V the wind V at best.
And please do not once more drag in tacking as that does not apply in this case.
So to sum up I am looking forward with great very great interest in the report from the NALSA on your tests runs.
No you won't. This is clearly you taking your exit and hoping it all goes away.
And oh yes I will be back to witness Newton being proven wrong.
And why are you guys still trying to sell this so hard if you happen to have some sold proof coming on line in a matter of weeks?
In fact feel free to used this website mail feature to let me know when the NALSA report had been released.
