Boeing B-29 Superfortress vs. Millennium Falcon

Next you're Going to tell me the empire uniforms look like Nazi ones!

They made the original ships and vehicles for Star Wars by taking existing model kits and mix and matching parts (aka kitbashing). This part of the Millennium Falcon model likely came from a B-29 or similar model set.

Greenhouse cockpits predate the B-29 by many years. The He-111 has it for example.

Bah, neither can jump to Ludicrous speed.
