Re: [Flightgear-devel] Vostok-1

I've never looked into it, but I've always wondered how (or how much)
control they have over those giant rockets.  I know the space shuttle flies
a very precise profile and rolls over at a particular point, so they must
have some good control.  But I have never thought about how that control is
implemented.  Do they have secondary thrusters?  Can they vector or deflect
their thrust?  Can they throttle?  I know that some smaller rockets will
spin along their longitudinal axis to help average out any built in
imbalances and keep a stable course (probably the same idea as a rifle
bullet.)
