Blueprints (Ref Images)

Hello, I just wanted to ask people if they have any links for some kind of blueprint site, such as blueprints for cars, airplanes, ships, architechture. I can never find any good blueprints and have to end up googling the thing i want, which rarely turns up any good results. If anyone has anything to share please post. Thanks.

My fave is this Russian site. If you don’t speak Russian, you’ll still get to the goods easy enough: Ugolok neba
