Any FOOL can take off in a small plane but to land one that's an entirely different matter

 So, when the pilot passed out and his passenger had to make an emergency landing the first thing you would need is someone with enough calmness and intestinal fortitude in order to pull this off to begin with.  I can remember with an instructor taking a plane with an engine off from a runway for the first time. At the time the instructor was a World War II Fighter pilot who wanted to demonstrate to me how macho he was. Just taking the plane off in a 20 mph cross wind where my left wing almost touched the ground during the takeoff had already used up most of my macho by the way. Then this instructor seemed to want to scare me to death more than anything else (maybe his fighter pilot instructor was like this for him in order to see if he had "what it takes to fight and die as a fighter pilot". I don't know. 

Anyway, this flight instructor decided I needed to experience stalls which is likely the most terrifying flying exercise you can do other than taking off and landing in bad weather or a cross wind. So, that is what we did. After doing this 3 times I told him he needed to stop because otherwise I was going to throw up all over the plane.

What is a stall?

This is the most physically advanced maneuver a pilot is taught other than landing a plane in bad weather or cross winds of higher velocity. What you basically do is to keep the nose rising without increase power to the engine. Eventually the wings of the plane stall in the air and the plane falls about 1000 to 2000 feet and hopefully you can recover from this without crashing the plane into the ground.

So, obviously you want to be over 5000 feet in elevation and it's better if you are 7000 feet to 10,000 feet so you have more time to recover before you crash into the ground. So, as you slowly bring up the nose without increasing power to the engine eventually the plane starts to fall down and a little backwards so you feel like you might a little at a really intense carnival ride of some sort that causes you to drop a distance quickly.

Except in a stall in an aircraft you aren't tied to anything you are like a kite in the wind. And the other problem is many planes might crash in an uncontrolled stall because their design is not conducive to pulling out of a stall.

The two best planes for recovering from a stall usually are the Cessna 152 (or 150 and the Cessna 172 also. Other planes if you stall them it's possible you might die.

The Cessna 152 and 172 if you release the yoke (steering wheel) while in the stall usually the plane will automatically recover from almost any stall by itself.

I met a pilot who almost crashed into the ground in a 172 in a stall before he remembered his instructor saying that you let go of the yoke(steering wheel) and the plane will recover from a stall. So, when he landed after releasing the yoke and recovering doing this he crawled out of the plane and kissed the ground because he was so shaken up he couldn't even walk. 

But, eventually he bought a plane and kept flying anyway even after almost dying in a stall.
