Nose section of "Fertile Myrtile" inside the hangar at Fantasy of Flight. Delivered to the USAAF with s/n 45-21787, it was one of four B-29s transferred to the US Navy for long range search operations with the designation P2B-1S. BuNo 84029 was loaned to NACA where it was converted to a mothership to launch the D-558-II Skyrocket. Test pilot Scott Crossfield was the first to exceed Mach 2 on 20 Nov 1953 after release of the Skyrocket from the P2B. His signature with "MACH 2" below it can be seen next to the nose art. D-558-II NACA 144 and NACA 145 launches are represented on the panels.

What a beauty! This Kingcobra is based right here in Atlanta

George AFB Air Show 1978. Owned by the American Air Museum. Painted in the markings of the National Advisory Committee for Aeronautics (NACA) which was the forerunner of NASA.

Ex NACA 127, USAAF 44-84900. Preserved by the USAF Museum at various locations from 1954 until 1994, when it was traded for four fibreglass replicas. First flight following restoration was on 1 July 1998.

Undergoing maintenance at home base, shortly after having been painted with its original yellow NACA tail markings. Built as B-29 45-21787. Transferred to US Navy as P2B-1S BuNo. 84029. Previously used as inflight launch aircraft for the D-558-II SkyRocket.

An early Kingcobra, 42-68941 was kept by Bell aircraft for test and development work. Transferred to the NACA (predecessor of NASA) in 1945, it did some flying out of Moffat Field, CA until sold as surplus circa July 1946. Becoming NX75488, the aircraft did little flying over the years in private hands. Acquired by the Confederate Air Force in late 1975, the fighter was displayed in French Air Force colors. A restoration was begun in 1999 with the aircraft flying again in 2017 as N919H with period NACA markings.

At the former Castle AFB, which housed a SAC B-52 and KC-135 training Wing. The B-29 was airworthy and had flown in from the Edwards AFB Open Day on the previous day.

In NACA markings with additional USAAF insignia.

Previous marks include Bureau number 84029 (Navy designation P2B-1S) and USAF serial 45-21787. The mission markings denote test flights carrying the Douglas D-558-II Skyrocket research aircraft. This aircraft was later sold to the Kermit Weeks' Fantasy of Flight museum in Polk City, Florida. However only its forward fuselage is on display there, with the remainder of the airframe reportedly stored in Ocotillo Wells, CA.
