At the end of Spaceballs there is a scene set at a diner / gas station / space station thing.
Here we clearly see several Winnebago style ships as well as the Millennium Falcon.
Are any of these other vehicles from other properties?
One of them sort of looks like a NASA space shuttle (with the top ripped off). Another has the look of a flying saucer, and then one looks like a Concorde jet.
