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.

Chapter One: Definition of Topic and Domain of this Study
The objective of the overall program for which this paper has been prepared is to
understand the physics and the engineering of advanced aerospace weapons system
applications ... into the future, e.g., from now through the year 2050. This study
addresses the clinical medical signs and symptoms and biophysics of injury known and
expected from unintended exposure to anomalous systems.
A. WHAT IS ADDRESSED IN THIS REVIEW
Advanced aerospace technologies, as with current technologies, often involve exposure
of humans to exceptionally strong, and in the future to likely exotic, fields. This review
is meant to cover the clinical medical injurious effects, including harmful psychiatric/
psychological effects on the human organism that may be induced. Specifically, we are
interested both in the more narrow scope of certain near-field heating and burn effects
on "biological tissues" [usually human] and also systemic or internal medical/
neurologica l / psychiatric inj ury or sequelae, usually modulated by neural tissue.
"Near Field" is a term we intentionally leave as subjective. That is, we include effects of
possible exposures that are within sight of the injured, and which are acute [within
hours] or subacute [within days], but not longer chronic effects. Our working distance
from the putative emitter is '!Os of meters, and injury times are less than 10 minutes.
We thus focus on the acute and subacute high-level, not chronic low-level exposures
and effects. The most important bandwidth of interest is the range with tissue effects
on humans: from about 300 kHz to 300 GHz; that is, from about 1 km to 1 mm wave
lengths.
In particular, we note that many of the effects on tissues {as currently with all
environmental exposures of Non-Ionizing Electromagnetic Radiation (NIEMR), toxic
effluents, and noise/ thermal effects} are initia lly incorrectly adduced to be
"subclinical" until chronic effects of low-level effects and/or accumulative doses are
recognized . We will be particularly cognizant to not miss this subtlety in determining
harm to persons in the near-field of possible advanced aerospace systems. We will not
(except by reference) discuss ionizing radiation tissue effects, unless they are adduced
to be "Mixed Field", e.g. the Cash-Landrum case, vide infra) .
Therefore, since the potential deployment of advanced weapons technology is
subsumed under this topic, of interest are not only side effects associated with possible
lift/propulsion field mechanisms of advanced craft architectures, but also effects from
advanced weapons systems as well. These include but are not limited to beam
weapons, and active denial systems (ADS), including high powered microwaves (HPM).
B. WHAT IS NOT ADDRESSED IN THIS REVIEW
We are aware of claims that some new and emergent systems may be intended to
cause harm, and thus even be an intended weapon system. We make no attempt
herein to validate any claims. There is ample precedent in US history for utilizing a
separate analytic framework for Verification and Compliance issues, as in the lag in our
recognizing Former Soviet Union and Chinese systems utilizing infrasonic, laser
blinding, and NIEMR weapons that went unappreciated by our intelligence agencies for
two decades. Historically, the IC (Intelligence Community) adduces verification first,
