Fastwalkers
Fastwalkers is a term used within the UFO research community to describe unidentified flying objects that move at extremely high speeds across the sky, often far exceeding the performance capabilities of known aircraft. The label generally refers to objects tracked visually, by radar, or by space‑based sensors that appear to travel in straight trajectories at remarkable velocity, sometimes entering or exiting Earth’s atmosphere without visible propulsion systems or aerodynamic control surfaces.
The term “Fastwalker” is documented in connection with North American Aerospace Defense Command tracking language. One of the earliest publicly referenced uses dates to a 1984 NORAD incident in which a Defense Support Program satellite, often identified as DSP‑7, reportedly tracked an object for approximately nine minutes as it traveled at over 22,000 miles per hour toward Earth before altering course. Available documentation indicates the object was classified as non‑missile and non‑debris at the time of detection. Declassified material later indicated that a fastwalker database extended back as far as 1972. In official usage, the term was applied to unknown objects entering from space that did not correlate with known satellites, missiles, or catalogued debris. Over time, the designation moved beyond classified tracking terminology and became widely adopted within civilian and investigative UFO research circles to describe high‑velocity unidentified aerial targets.
Fastwalkers are often associated with detections made by Defense Support Program infrared satellites, which monitor missile launches and other heat signatures. In certain reported cases, these satellites have registered intense infrared sources entering or maneuvering within near‑Earth space that did not match known aerospace activity. Declassified 1990s material indicated that DSP systems routinely detected objects that were not ultimately categorized as missile launches or known space debris. Some defense tracking systems have categorized such detections as Uncorrelated Targets or Unknown Satellites when confirmed on multiple sensors yet lacking identification. In contrast, “Slowwalkers” has been used in some internal contexts to describe slower, aircraft‑like or orbital anomalies that also resist immediate classification.
Reports of Fastwalkers have emerged from amateur skywatchers, trained military observers, radar operators, and government agencies across multiple continents. Accounts span decades and appear in the United States, Russia, parts of Europe, and elsewhere. In many cases, these objects are described as bright points of light moving faster than conventional aircraft, sometimes changing direction abruptly or accelerating in ways that appear inconsistent with conventional aeronautical engineering.
One of the defining characteristics attributed to Fastwalkers is velocity. Estimates from witness accounts and radar data analyses have suggested speeds reaching tens of thousands of kilometers per hour, with some analyses citing figures above 35,000 kilometers per hour, or roughly Mach 28 under atmospheric comparison models. In reported incidents, the objects have exhibited sudden right‑angle turns, instantaneous acceleration, hovering behavior, or rapid altitude shifts. These maneuvers challenge traditional aerodynamic models, as conventional aircraft require gradual banking, sustained thrust, and structural limits that constrain high‑speed directional changes.
Government acknowledgment of unidentified aerial phenomena has further intensified interest in high‑speed objects. In 2017, investigative reporting revealed the existence of the Advanced Aerospace Threat Identification Program, active from 2007 to 2012, which examined military encounters with unexplained aerial objects. The effort operated alongside the Advanced Aerospace Weapon System Applications Program, the contracting vehicle awarded in 2008 that funded related research. Approximately 22 million dollars were allocated through AAWSAP, which examined a broad range of anomalous aerospace and related phenomena in addition to conventional threat analysis. Subsequent disclosures indicated that elements of investigation continued informally beyond 2012.
In 2020, the U.S. Department of Defense officially released three declassified U.S. Navy videos commonly known as FLIR, GIMBAL, and GOFAST. The footage shows fast‑moving objects displaying unusual flight characteristics. Although labeled as unidentified aerial phenomena rather than specifically categorized as Fastwalkers, the rapid motion and unconventional behavior observed renewed broader discussion surrounding high‑velocity unidentified objects.
More recently, the establishment of the All‑domain Anomaly Resolution Office formalized government reporting on unidentified aerial and space‑based events. Public reporting through fiscal year 2024 indicated a cumulative total of 1,652 UAP cases reviewed, including 757 new reports in the 2023 reporting period.
Requests for additional Fastwalker‑related documentation have, in some instances, been denied or partially withheld under national security exemptions, reflecting the continuing classified status of certain space‑tracking capabilities and sensor systems. As a result, public understanding of the full scope of space‑based detections remains limited.
Internationally, high‑velocity unidentified objects have also been discussed in relation to events such as the 1989 Phobos‑2 probe observations near Mars and radar‑tracked cases like the 1976 Tehran incident, which involved both visual sightings and reported instrumentation effects on interceptor aircraft. Civilian agencies such as France’s GEIPAN have examined rapid aerial anomalies within their national reporting frameworks, contributing to the broader global context of high‑speed unidentified phenomena.
Several researchers have explored the subject of Fastwalkers in depth. Jacques Vallée has argued that unidentified aerial events should be studied within a broader interdisciplinary framework that may extend beyond conventional aerospace explanations and could intersect with questions of physics, perception, and information systems. Richard Haines, a former NASA research scientist and Chief Scientist for the National Aviation Reporting Center on Anomalous Phenomena, has analyzed pilot reports and aviation safety implications tied to unidentified aerial encounters, including cases involving reported electromagnetic effects on aircraft systems. Some researchers connect high‑velocity objects to discussions of non‑human intelligence or unconventional physics, while others maintain a strictly aerospace or sensor‑analysis perspective.
The concept of Fastwalkers appears in major works examining UFO history and government investigation. UFOs and Government: A Historical Inquiry by Michael Swords and Robert Powell presents detailed analysis of official categorization systems. John B. Alexander’s UFOs: Myths, Conspiracies, and Realities addresses military encounters and classification practices. Beyond UFOs: The Science of Consciousness and Contact with Non‑Human Intelligence by Rey Hernandez, Jon Klimo, and Rudy Schild approaches unidentified aerial phenomena from a multidisciplinary standpoint that includes high‑velocity cases within a broader framework.
Despite ongoing debate regarding origin, classification, and explanation, Fastwalkers remain a persistent category within contemporary UFO discourse. As official transparency efforts expand and space‑based monitoring systems grow more sophisticated, the study of Fastwalkers remains connected with larger discussions surrounding unidentified aerial and space phenomena and their implications for security, science, and human understanding.
