• An anonymous X account (@TMBSPACESHIPS) focused on exotic plasma/electric propulsion went completely silent on February 27, 2026 — the exact day retired Maj. Gen. William Neil McCasland disappeared from his Albuquerque home.
• The account’s bio contains deliberate “errors” (38 years service instead of 34, wrong universities) consistent with McCasland’s pattern of ambiguity and plausible deniability seen in WikiLeaks emails.
• In 2023 the account posted a hand-drawn 1998 schematic from a KC-135 cockpit sighting: a bright object making sharp 90° altitude drops from ~150,000 ft to 90,000 ft, trailing a 100+ mile multicolored ionized helium tail with specific plasma emission colors (royal green, etc.).
• Image enhancement revealed bleed-through text on the back: a detailed component list (Electron Gun, Continuous Marx Generator, Helium-3 Ion, Beryllium Oxide, Thorium, etc.) that reverse-engineers the observed phenomenon into a plausible pulsed-power plasma propulsion system.
• The technical knowledge displayed (hands-on ionized helium experiments, Crookes dark space, specific material properties for directed-energy/pulsed-power systems) aligns closely with McCasland’s classified career commanding AFRL labs, Phillips Research Site, Space Based Laser Project, and Riverside Research board role — despite his public PhD being in a different field.
• Phonetic misspellings (“Crooks,” “FIOURESENT,” etc.) may be intentional degradation for deniability or simply informal lab shorthand from someone more verbal/oral in technical learning.
• The account’s entire 1,645-post history obsessively explores ionized gas propulsion, anchoring on the 1998 observation — no public publications match this body of work, consistent with classified programs.
• As of March 11, 2026 (Day 12), McCasland remains missing; BCSO/FBI/Kirtland are involved, Ross Coulthart has framed it as a national security crisis tied to UAP disclosure, and search efforts reference “advanced technologies.”
