Documents / Official release
This Defense Intelligence Reference Document, dated 11 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications program. It reviews reported injuries to people exposed at close range to anomalous aerospace vehicles and attributes them mainly to electromagnetic radiation field effects, including burns, neurological and auditory effects. It argues that clinical diagnoses can help infer the characteristics of advanced systems. The appendices hold a case catalog and ICD code tables.
From the source: Release of 2026-09-18 Incident: 3/11/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys reported acute and subacute injuries allegedly associated with close exposure to anomalous field effects, attempting to draw tentative parallels between these claimed symptoms and the known physiological effects of intense radiofrequency .and microwave exposure on human tissue. By reviewing medical and biophysical literature on heating, burns, neurological effects, and sensory disturbances, the report speculates on theoretical mechanisms by which intense electromagnetic fields might account for some of the reported injury patterns, though it does not establish a direct causal link between the reported injuries and any specific source. It hypothesizes that clinical symptoms and reported exposure circumstances might allow for highly constrained, limited inferences regarding the characteristics of an unknown emitter or propulsion system. Notably, the document’s findings rely heavily on case comparisons lacking physical examinations, untestable exposure conditions, and a mix of established science and more controversial literature. These comparisons are then extended to anomalous-craft scenarios, attempting to map known electromagnetic injury mechanisms onto anomalous encounter claims that lack independent scientific validation in the report.

The Airborne Instruments Laboratory {AIL}v in 1956, reported for the first time
anecdotal evidence that persons could "hear" RF frequencies [10], The data were
however, deemed important enough to be placed in a corporate advertisement and
warning.
Yet, the first systematic review of evidence and experiment of what is now known to be
human capability to "hear" modulations in ears or the temporal lobes, as well as in the
apparatus of the inner ear (the "cochlear microphonic") was not published until 1961,
followed by a series of eight peer-reviewed papers over the following decade.vi
The most comprehensive review that describes the biophysics and the methodology to
modulate RF to incorporate purposive communications, and which also describes in
detail injury patterns was published in 2003, by the Motorola Research Laboratories,
and is still the seminal meta-analysis {of about 100 review articles} on these subjects
[11].
For our purposes, it is sufficient at this point to summarize this and additional literature
[esp. 11-15] in contexts narrowly related to claimants' description of effects when
placed near (10-100 meters) of a presumed emitting large object, which may or may
not have the appearance of containing an obvious RF antenna:
• The mechanism of transduction of the RF may be to or through skin, bone, or the
external auditory meatus.
• Frequency and pulse width dependency may account for perceptions as coming from
the ear, the temporal lobe on the same or contralateral side to the object.
• The frequencies are amazingly broad: contained with the bandwidth of 2.4 - 10,000
MHz {MF, HF, VHF, UHF, SHF, EHF; wavelengths 1km - 1cm; incident energy
densities of 10-20 mJ/kg threshold; 40 μJ/pulse, energy absorption per pulse 16
μJ/g},
• Thus, the character of the perceived sounds can be used to accurately "back
calculate" the emitter characteristics: many thousands of human experiments over
the above ranges have been consistent and repeatable.
• Simple shielding, includ ing tin-foil hats (sic!) will attenuate and often block totally
the sounds and communications.
Voice frequencies of 5 kHz-20 kHz can be RF modulated, and transmitted covertly, with
intelligible effect. However, it is absolutely required that to hear the sounds, a human
must have a capability to hear a frequency acoustic wave in the kHz range above 5kHz
through 20 kHz.
v AIL was formed in 1945, in Mineola NY by then Defense Department contractors affiliated with MIT. It became the
forerunner of virtually every subsequent application Radar and EM laboratory, especially for the Department of the
Navy. It is known in folklore, as having been the site of the development of the technology for the controversial
"Ph iladel phia Experiment." http ://www.stealthskater.com/Documents/AI L 0 1.doc
vi There are at the present time, over 240,000 peer-reviewed scientific papers on the phenomena of RF hearing and
covert communication, with and without engagement of the inner ear, in the medical literature. Yet, to this day,
persons who during experiencing of anomalous RF hearing and skin heating when confronted by unknown objects
in the near-field are nonetheless ubiquitously {at first, at least} said to be paranoid, or paraphrenic, or paranoid
schizophrenic.
