Nah, it's cool man. I can understand the technicalities of things. I bet a hangar is actually USED whereas a warehouse tends to just stock things. Oh I don't know... lol

HANGAR - A covered and usu. enclosed area for housing and repairing aircraft.

WAREHOUSE - A place for the strorage of merchandise or commodities.
