Why did the pilots wore scarves

scarves in early explorers of the sky were not the only smart article of clothing, performing a useful function for the pilot.

At the dawn of aviation technology was rather primitive - there was no radar or other tracking systems of the enemy. Therefore, in a dogfight to stay up to date plans of the enemy, the pilot had to constantly turn my head, looking for the enemy. Because of this pilot he rubbed his neck, often rubbing her blood. Therefore, the pilots began to wear silk scarves, which protected the neck from rubbing.
