Model of the X-24 Research Vehicle, measuring 24″ long and 8″ wide, set upon a wooden base with a plaque reading, "NASA Flight Research Center." In very good condition, with a large chip to the corner of one wing and some scattered scuffing. The X-24 was an experimental aircraft developed from a joint USAF-NASA program experimenting with a lifting body design to demonstrate the concept of unpowered reentry and landing.
