For example, take a look at the following photo:
Why do you suppose Federal Express felt the need to specify that the truck provided "ground" transportation?
Does Federal Express own ships? Do you think they say "water" on them?
Do you think that their planes say "Air" on the sides?
What about when the planes are on the runway?
Aren't they actually "ground" at that point in time?
I'm just sayin'
