Found [web]

• A. G. Kelly, "Hafele & Keating Tests; Did They Prove Anything?" (affiliation HDS Energy Ltd, Celbridge, Co. Kildare). Dated 2000 by the wiki; a French summary is appended.
• Kelly states that he obtained the original 1971 test report by Hafele directly from the USNO (his ref. [14]: Proc. 3rd Dept. of Defense PTTI Meeting, pp. 261-288, 1971) and publishes per-clock results "for the first time".
• His Table 3 (ns): Eastward raw results for clocks 120/361/408/447 = -196/-54/+166/-97; Westward = +413/-44/+101/+26. The published H&K "second-method" values were -57/-74/-55/-51 (average -59) and +277/+284/+266/+266 (average +273), against predictions of -40 and +275 ns.
• He quotes the 1971 report: "Most people (myself included) would be reluctant to agree that the time gained by any one of these clocks is indicative of anything", and "the difference between theory and measurement is disturbing".
• Drift-rate table (ns/h) before and after each trip; he argues changes of up to about 4-5 ns/h in drift rate, against the -0.6 ns/h (East) and +3.4 ns/h (West) needed to accumulate the predicted shifts, make the test inconclusive. He says H&K made 14 rate-change corrections after the 1971 report.
• He cites Essen (1977, Creation Research Society Quarterly 14, 46) as reaching a similar conclusion earlier, and his own Monograph No. 3 (IEI, 1996).

Bearing on the claims

• Not about Sagnac directly. It bears on claim 3 (SR has no role) as the same author's challenge to a main experimental support of SR/GR time dilation, and it is a primary document of his method (going back to the raw data). Hafele-Keating is also tabulated in the project paper's comparison of "orbital rotation" (p.~9-10).
• These are Kelly's characterization of the 1971 report. The 1971 PTTI report itself is the record that would check his numbers (lead below).
