During the Belgian wave, F-16 interceptors were scrambled after ground reports and radar activity. Hall describes repeated radar contacts and rapid changes in target speed/altitude that frustrated interception, while treating the episode as part of a broader multi-witness wave.
Claims are displayed with the source wording, locator, relationship and verification state. Competing claims remain separate rather than being averaged into a single answer.
“Hall describes Belgian F-16 interceptors obtaining repeated radar contacts during the March 30–31, 1990 wave while the target reportedly made abrupt speed and altitude changes that prevented a conventional intercept.”
“The source treats the event as highly anomalous, but individual radar returns and their relationship to visually reported triangular objects remain an interpretive issue.”
“Hall says military UFO reports were continuous during the Blue Book era and that after the public project ended, reporting became more fragmented, restricted, or difficult to access.”
“Hall groups restricted-area incursions, interceptor pursuits, radar-visual cases and weapons-site events as especially significant because the witnesses and systems were tasked with air defense or security.”
