It's reasonable to mention that when there is any wind at all, a descending aircraft descends through a wind that usually slows and backs [which means its direction rotates anti-clockwise] near the ground - a matter of ground friction. Then within a half wing span of the ground, an added lift component is available - called ground effect....a plane descending through slowing air can end up with an air speed less than its stall speed and ends up crashing to the ground. This is a good intro mechanics problem.
