First photo is testing a ramjet engine and missile was also a ramjet unit books.google.co.nz/books?id=rqhnBwAAQBAJ&pg=PA115&lpg=PA115&dq=p61+test+flights+missile&source=bl&ots=AJluij4dyo&sig=8XtyJ6nL_1JwPG-k3tqKeJanugs&hl=en&sa=X&ei=Z1ejVQ_Cp9AE5Kiz8Ak&ved=0CCYQ6AEwAQ#v=onepage&q=p61%20test%20flights%20missile&f=falsealso from Wiki en.wikipedia.org/wiki/Northrop_P-61_Black_WidowIn 1948, the National Advisory Committee for Aeronautics (NACA) obtained an P-61C from Air Research and Development Command for a series of drop tests of swept-wing aerodynamic drones at Moffett Field, California. Much engineering data was obtained from these tests. An RP-61C, AF Ser. No. 45-59300, thus became the last operational USAF P-61 to be retired at the end of the NACA testing in 1953. A second P-61C (AF Ser. No. 43-8330) which was still flyable was obtained from the Smithsonian Institution by NACA in October 1950 for these tests, and remained in use by NACA until 9 August 1954, being the last P-61 in government use. This aircraft is now on public display at the NASM's Steven F. Udvar-Hazy Center.[21] P-61B-15NO, AF Ser. No. 42-39754, was used by NACA's Lewis Flight Propulsion Laboratory in Cleveland, Ohio for tests of airfoil-type ramjets. P-61C-1NO, AF Ser. No. 43-8357, was used at Ames as a source for spare parts for other P-61 and RP-61 aircraft.
