8 June 1966: During a publicity photo formation flight, a Lockheed F-104N Starfighter, N813NA, flown by NASA Chief Research Test Pilot Joseph A. Walker, was caught in the wingtip vortices of the North American Aviation XB-70A-2 Valkyrie, 62-0207, the second prototype Mach 3+ strategic bomber. The Starfighter rolled up and across the Valkyrie. The two airplanes collided, with the F-104 taking off the Valkyrie’s vertical fins, then exploding.

The B-70’s pilot, Alvin S. White, was able to eject, though he was severely injured. Joe Walker and B-70 co-pilot Major Carl S. Cross, United States Air Force, were killed.

Still photographs and motion picture film of the formation were being taken from Clay Lacy’s Gates Lear Jet. The photos were for a General Electric publicity campaign showing U.S. military aircraft that were powered by GE engines. Air Force procedures for requesting and approval of publicity flights were not properly followed and it is likely this flight would not have been approved had they been.

Reportedly, just prior to the collision, Walker radioed, “I’m opposing this mission. It is too turbulent and it has no scientific value.”

  1. Hi Bryan,

    I work in the marketing department for Clay Lacy and I came across your post above. Thanks so much for mentioning Clay Lacy.

    We really appreciate it, and were wondering if you could include a link to our website http://www.claylacy.com, so your readers can learn about Clay’s work more easily.

    Thanks very much!

    I look forward to hearing from you.

    1. Ms. Levinson, I would be happy to include the link. I began my civilian aviation career at VNY (way back in the last century) adjacent to Mr. Lacy’s hangar at the northwest corner of the airport. My employer’s helicopters were parked on the ramp next to the #64 P-51 racer and Miss America. . . Mr. Lacy is a legend in Southern California aviation.

  2. What a tragic and unnecessary loss of life. All to keep GE’s bigwigs happy for the sake of the almighty dollar. I hope GE got the publicity they were looking for.

    1. In 1966 the knowledge base of wingtip vortices and wake turbulence was still in its infancy. Assuredly NASA Chief Research Test Pilot Joseph A. Walker would have kept greater separation from the XB-70’s right wing tip given today’s exhaustive research.

  3. Unless I’m mistaken–and Ms. Levinson could answer this for certain–Lacy’s LearJet was down for some reason and he had to borrow one for the photo mission. The one he borrowed belonged to Frank Sinatra.

    1. A photograph at check-six.com is apparently the camera crew boarding a Lear Jet on the morning of 8 June 1966. The aircraft is registered N175FS. That N-number is currently assigned to a 1965 Learjet Inc. Model 24A, s/n 031. The current FAA-registered owner is Artemis Aviation Group LLC, Wilmington, Delaware. That address is a Delaware corporation service, the Delaware Registry, Ltd. There are no prior owners listed. . . That said, a website for Sun Lakes Aero Club does indicate that Sinatra owned the airplane until June 1967 when he traded it for a Gulfstream GII. The article describes a succession of owners, and further states that this was the photo plane.
