It looks like the main problem with the 747-100 configuration file is the
ground effect factor in the drag section. Here it is:

We see that ground effect starts at a height of about one wingspan.
Hi Dave,
So, here my ignorance of aerodynamics comes to the fore: Why does ground
effect reduce drag?

I thought it only affected lift?
It does both. It reduces drag by reducing the spanwise airflow, which gives
the wing a higher apparent
