I have read about them and they were horrifying.  The 163 was designed to land on its skid so it would be exempted from this.  I belly land myself often as well, particularly when landing at an airfield with many bad guys.  My intent was for a little more added realism.  
If you try to land faster than 180 you will crash and die, if you land with too much decent, you will die. 
I am looking for the added realism.  I belly land often enough myself.
