So many words and no substance at all .Do you have serial number of this “probably EF-111 ” (sic!) ,if not you are waste of bandwidth as usual Mr Painter .
On the starboard side, below the canopy rail, the name of the WSO is clearly visible. It reads “W.S.O. MAJ. D. PRIMAS”. On the port side is stenciled “Pilot” but the name has been removed. Below that it says “CREW CHIEF SSGT HET_ICK”, with the fourth letter unreadable. Elsewhere on the module is a partial identification of the aircraft: “F-111A NO.67-06_A” where _ is a missing number.
Three F-111As in the serial number range from 67-060 through 67-069 were lost officially.
They were : 67-063, lost 7 Nov 1972 : crewed by Robert Brown and Robert Morrissey (ref.no 1945); 67-066, lost 16 Oct 1972 : crewed by Hockridge and Graham (ref no 1939); 67-068, lost 22 Dec 1972, crewed by Robert Sponeybarger and William Wilson (ref no 1966).
