They were most likely flying the planes by hand. A perfectly straight
line can indeed be quite difficult to fly; corrections need to be made.
In the second WTC crash, for instance, you see the plane banking left at
the last minute and notice later that, while it dealt a most damaging
blow, it was a little right of center. The pilot was trying to make a
correction.
How hard would hitting the side of the Pentagon
be? (45 degree descent
apparently).
Harder than you think, even assuming a total lack of target defense
capabilities. Airplanes can't or won't always go exactly where you point
them. In a single-engine prop plane, for instance, gyroscopic precession
of the prop gives the plane an affinity for turning left. Other kinds of
I think it is more a matter of the aircraft wanting to roll left
(counterclockwise) in response to the propeller pushing air in a
clockwise direction.

planes have other issues. Vertical movement has
complications resulting
from changing airspeed. If you put the nose of a plane into even a slight
dive, airspeed will increase *quickly*. You've got to arrange some way of
decreasing airspeed (throttling down the engines, extending the flaps,
etc.), or else the plane will soon begin to break apart. A 45-degree
angle seems horribly steep.
