<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>Yeah, like just
as if another airplane were to plow into the side of it back by the vertical fin
it's going to rotate, but "only if it's fastened to the ground".
(Wow)</FONT></FONT></DIV>

<DIV><FONT face=Arial size=2><FONT face="Times New Roman" size=3>Oh yeah, I
agree that the airplane flies straight into the "freestream", but this deviation
from our parallel flight path is generated by the force of the crossing air, the
effect of which is produced by the fact that the lever arm of the vertical fin
is 2+ times the length of the nose (from the C.G.) multiplying the side
force aft and thus creating the offset.</FONT></FONT></DIV>

<DIV><BR></DIV><WBR> The airplane doesn't "know"
anything.<BR> It doesn't know that when air pressure is less on any one
side of it that it's supposed <BR>to go in that direction. It doesn't know
that when we apply throttle, it's supposed to <BR>go forward. We create these
situations with inputs and the airplane responds. The <BR>airplane doesn't
know to fly slower against the wind, and faster down wind. It's a matter<BR>of
physics and what the airplane is designed to do. If wind is forced against the
side of <BR>the airplane, no, it does not know what's going on, but it will
react. Just as if another <BR>airplane were to plow into the side of it. It's
going to
move.<BR>
