It was (a very unusual I must confess) part of my PPL instructor course to land a C152 with the doors alone. Set the power so that it will just climb a tiny little bit, 100ft/min maybe, and tighten the lock of the throttle lever. Then unlock both doors and push them outwards with your arms as needed, an adult's armspan is large enough to do that alone. One at a time for turns and both toghether to turn that little climb rate into a shallow descent. No problem to land it that way provided the runway is long enough and not too much wind.
