Speed Limit Enforced by Aircraft Sign

When I was a kid and first read the sign on the side of some highways that said "speed enforced by aircraft," I was pretty sure that meant that if you were speeding, planes would come down and blow your car up. Well, that turns out not to be the case. Honestly though, are speed limits still, or ever were, being enforced by aircraft? Seems like hitting a fly with a hammer, or the other way around.
