Boeing WB-50 Superfortress (8522)

In the late 1940s, a significantly modified version of the B-29 was developed and designated B-50. One of the B-50s nicknamed "Lucky Lady II" made the first non-stop flight around the world, departing westward from Carswell AFB, Texas, and returning 94 hours 1 minute later having flown 23,452 miles. The B-50 was the last propeller-driven bomber delivered to the USAF. After being replaced by the B-47, they were relegated to other duties. This aircraft at Castle Air Museum was assigned to the Weather Reconnaissance Squadron at McClellan AFB, Sacramento, California, where it performed weather tracking and atmospheric sampling after Soviet nuclear weapons test. B-50s served until 1964.
