Air Unit Hex Visibility

[Compass Rose]

Does anyone know why when using Air Recon, or any of the other type of air unit, the controlling player does not get to see any of the hexs that the air units used as a flight path and/or any adjacent flight path hexs?

I would think that if any air unit was used, seeing several hexs, instead of just seeing a few during a recon flight, and only being able to see one hex during a fighter/bomber mission would be possible since this would be a realistic.

Thanks
