Default Why does the shuttle throttle on ascent?

During the few test shots of Trident missles that I have seen, I always
thought that the angle at which the vehicle flew was remarkable; like
nothing I had ever seen, save for the occassional errant Estes rocket.
The angle seemed close to 45 degrees, although I had no way of really
knowing, almost immediately after emerging from the water and ignition.


I wonder, though, if it actually ascends in that direction, or if that's
just a transient error -- perhaps something to do with the dynamics of
breaking the surface -- that the guidance system sorts out a second or
two later.
