Planes would be (marginally) safer if the seats faced the rear of the plane, but people generally find that uncomfortable, so it's not done.
The incremental safety benefit of being rear-facing vs. front-facing for an airplane carseat is minimal, though.
My question is why people want to put their carseat on a plane rear-facing when it does not matter? It is not a car. You usually do not have direct impact.
And dangerous turbulence is extremely rare as well.
