Yeah, I thought so. The CM had thrusters that can roll it only- no pitch and yaw, but the center of mass was arranged for re-entry so the blunt end was presented 27 degs off square and the whole capsule behaved as a wing at high speed. They flew either heads up or heads down to flatten or steepen the approach path, and could roll up to 15 degs either side to steer without affecting lift. Every Apollo re-entry was flown entirely by computer but they had the option to take manual control and fly by instruments.

After the first few lunar flights they were so accurate with their landings they were worried about hitting the aircraft carrier, so they moved the carrier a few kms away from the center of the landing zone!

I had previously thought that re-entry was entirely ballistic.

There's lots of other interesting stuff in the book as well (I think).
