When I was flying with the Dept. of Natural Resources as a fire spotter right after I retired I got many hours of free flight lessons from the pilot (he was a certified flight instructor). I got quite comfortable flying that little Cessna 172 as long as it was up in the air. One evening as we were landing for the day I kept waiting for the pilot to take over. All he kept saying as he was talking me down was "you are doing fine". I was a nervous wreck but I landed the plane. To this day I don't know just how much "help" he gave me (he said I did it myself) but I do know there is a BIG difference in keeping a plane level in the air as compared to landing one.
