Results of research on Ft. Smith chevron sighting.

This is a follow-up to my recent post here regarding the specific chevron-shaped object. I have since done some research that would dispel two of my theories.

I contacted a retired B-58 crew member who confirmed that the leading edge of the wing did not glow when supersonic.

I have also researched the possiblity of the XB-70. The Final Report on the the XB-70 program published in 1972 lists every flight of each of the giant delta wing aircraft. A/V-2 had already crashed by the time of this sighting. A/V-1 was flying.

I have been unable to determine if the XB-70 did any night flying, or flying significantly away from Edwards AFB, CA. From reading the chief test pilot's summary, I would highly doubt that this aircraft did either. It was a very complex aircraft, often having malfunctions requiring unique support. To intentionally stray from its support base would be doubtful.

Also, it was a very crudely equipped and instrumented aircraft in its experimental form. Its single TACAN worked poorly, requiring the crew to rely heavily on FAA ATC for help with navigation.

There is one long-shot date of possibility. The aircraft flew on 8/24/67 for over two hours, reached over Mach 2, and an altitude of 58,000 feet. If the actual sighting that I witnessed occured on this date, it would be an interesting coincidence.

So, I believe that leaves this sighting on mysterious footing. Other possible aircraft of the day are the CIA A-12 Blackbird and its followers, the YF-12 and SR-71. That will take more research and will probably be more difficult to find records in the public domain.
