Reminds me of the F/A-18D - F-5E "near miss" reported in the article by G. L. Koelzer in the February/March 2006 Air & Space.
ACM in 2002 at MCAS Yuma, Arizona. The F-5E crossed the flight path of the Hornet belly-on, from right-to-left at exactly the same flight level. The Hornet pilot reporting both hearing and feeling the J85s of the F-5E.
The instrumentation aboard both aircraft (used for post-flight reconstruction & evaluation of the action) showed the "miss distance" as "1 foot, plus or minus 3 feet"!
I have scanned the article into a WORD ducument, and also the computer-generated "closest-approach" image (which shows the aircraft interpenetrated), but as it is a copywrited article, I don't know if it would be allowable to post it here (I know others do, but I want to know for sure).
