Nevertheless I think stealing GA aircrafts and using them for either
fly-by shootings or in combination with explosives is a real threat

Why steal an airplane? Isn't it easier just to rent one?

(and even harder to counter than your Oklahoma-bombing truck).

It's true that you can protect a specific target from a truck-bombing by
erecting barricades to prevent traffic from approaching. In that limited
respect, plane-bombings are harder to counter.

However, it's of no use to protect a specific target as long as many other
equally attractive targets remain accessible. Protecting all such targets
would require permanently shutting down traffic in entire cities, which is
impossible. Additionally, you can carry a much greater explosive payload in
a truck (or even a car) than in a typical GA plane. So on the whole, car-
and truck-bombings are the greater threat.

Making
sure that airports are properly fenced in and have a metal
detector/x-ray machine could be a reasonable deterrent.

Since car- or truck-bombings are a greater threat on the whole, should we
also have to fence in all parking lots and garages, and screen everyone
there with metal detectors and x-ray machines?
