To simulate combat missions for the American bomber force, the Air Combat Command conducts low altitude training flights along routes throughout the USA. This paper presents the results of an effort to evaluate the effect of these overflights on the many archaeologically significant structures located beneath the training routes. This study has shown that: (1) low overflights can induce measurable vibrations in these ancient structures; (2) the overflight induced motions do not constitute an appreciable threat to the sites; and (3) the observed levels of motion are no greater than those induced by sources in the natural environment. Although these findings are specific to overflights by B-52s, comparison of the low frequency acoustic signature of the B-52 and that of the B-1B suggests that B-1B overflights should not pose a significantly greater threat to the structures than B-62 overflights.
