Did Apollo really travel sideways?

The "flying sideways" you saw is likely a depiction of the spacecraft using "Passive Thermal Control" or "barbecue mode", in which the spacecraft is traveling sideways relative to the direction of travel and to the sun, and rolling at a very slow rate, in order to keep the sunlit areas from getting too hot, and the shadowed areas from getting too cold. Once in orbit about the moon is getting yourself double IR/FIR at least half of the time, regardless of whatever direction they are pointed, as well as getting their DNA gamma and hard-Xray traumatised at the very same time. There's even a little earthshine/planetshine IR to deal with. Rather odd that Venus was never once visible, especially since Venus shows up in most any solar system simulator, plain as day and otherwise much brighter than day. - Brad Guth - "whoever controls the past, controls the future" / George Orwell |

I wonder if it was to enable maneuvering, like LM extraction, which would be a bit hard to do with nozzle at the rear. With the spacecraft in a sideways orientation, it could carry out its maneuvers and proceed to the moon at the same time and speed without having to stop, turn round, get the LM, turn round and fire up again.
