-If the baggage door on a 177RG pops open (as it frequently did to when I used to fly them) it can be closed in flight by putting down full flap when the resulting downward airflow pushes down on the top of it
-Some pilots doing ICUS with you like to touch the controls in the aircraft, such as retracting 40degrees of flap in the 206 just before the flare or even the throttle just after takeoff. Both can result in a rather solid landing. If they do this, dont stand for it.
