english: For one thing, if this was just the Ebbinghaus effect, then we would expect the moon illusion to disappear for pilots flying high above the clouds since there wouldn't be any other smaller objects near the horizon.
non_english: Napríklad, ak by išlo len o efekt Ebinghausovej ilúzie, tak by ilúziu nemali vidieť piloti, ktorí letia vysoko nad oblakmi, keďže sa tam nenachádzajú žiadne menšie objekty blízko horizontu.
