What spotting aircraft could sense from heavy shells

Could a spotting aircraft see large naval shells glowing in flight from friction?

Usually not, but the turbulent wake of passing shells could be noticeable and could affect the aircraft.

Big-gun shells did not normally appear as clearly glowing objects that an observer could follow through the air. Visibility depended on the era and the aircraft's altitude, but the projectile itself was generally hard to see. The shell's passage produced substantial turbulence, however. An aircraft flying in the wrong place could feel that wake and have its flight disturbed, giving the observer physical evidence that shells had passed nearby.
