I was wondering if instead of wasting fuel on re-entry and landing it would be possible to slow down and maneuver the booster rockets towards their landing zone using the Magnus effect, e.g. by making them spin horizontally around their axis to convert downward movement into horizontal...
The Magnus wing effect is not very efficient, but that does not matter here as there is a lot of speed and height to be lost. Maintaining rotation should be quite easy.

Then I found this site, by NASA. Guess they already know. So it probably won't be feasible. But one can dream.
