On November 1, a Learjet 60 (N722BD) that allegedly left Austin for the Bahamas went into a steep, high-speed dive and slammed into a residential stretch of Military Trail in Greenacres, Palm Beach County — roughly six to eight miles from Mar-a-Lago. All nine people on board were killed. The impact opened a large crater and produced a fireball that, to anyone watching from the ground or on dashcam footage, looked a lot like a missile strike. At the same time, the public has just seen photos of Avenger short-range air-defense systems (Stinger missiles on Humvees) sitting on a barge in the Lake Worth Lagoon next to Mar-a-Lago and at the nearby airport. NORAD and U.S. Northern Command placed them there at the Secret Service’s request. When a tracked civilian jet drops almost vertically, punches a crater, and erupts in a fireball that close to those defenses, the natural reaction is to ask whether the pieces are related — and whether the jet was hit by something launched from Cuba, a ship in the Atlantic, or somewhere in the Gulf of Mexico. That question is fair. Flight-tracking data shows the aircraft departing Austin, climbing normally, then, near the West Palm Beach area, briefly climbing before entering a steep right-hand descent. Descent rates quickly exceeded 20,000 feet per minute and reached or surpassed 32,000 feet per minute. The last radar point was near 8,750 feet. ATC radio calls captured by LiveATC add important context. The crew reported light clear ice, an outside air temperature of about –47 °C, and moderate turbulence that was bouncing the airplane by hundreds of feet. Scattered storms were in the area; the jet had just passed through a stronger cell. Moments later they declared an emergency: they were descending at 8,000–10,000 feet per minute, then in an overspeed condition descending at 20,000 feet per minute, and finally told controllers they were going to crash into the ground. Videos from the ground show the steep nose-down impact that followed. When several tons of aircraft hit pavement at those speeds, the kinetic energy (which scales with the square of velocity) is enormous. The nose and engines act as a penetrator, and the sudden rupture and ignition of the fuel tanks produces the fireball and outward excavation that enlarges the hole. High-speed aircraft impacts routinely leave exactly this kind of crater and debris pattern; investigators use those features to reconstruct impact angle and speed. The result can look nearly identical to a missile strike to anyone watching from the ground. Why the defenses were there The Avenger missile-defense systems were installed at Mar-a-Lago in late October at the Secret Service’s request. Yikes! The Service has described a “heightened threat environment,” citing a roughly 40% year-over-year increase in threats against its protectees, a “persistent and substantial” airborne threat vector at Mar-a-Lago, more than 60 aircraft intercepts of restricted airspace near the estate since early 2025, past domestic assassination attempts, and U.S. intelligence warnings about intensified Iranian targeting of American officials. The systems are short-range defensive weapons intended to protect against low-flying aircraft, drones, or similar threats. They can respond faster than scrambling a fighter. They do not explain a civilian flight that was tracked from Texas and whose final moments match a loss-of-control dive rather than an intercept. Could a missile have come from Cuba or the surrounding waters? Geographically, yes. Cuba is only about 90–100 miles from Key West and roughly 250–300 miles from Palm Beach. That distance is well within the range of many modern cruise missiles. Russian ships that occasionally visit Cuban ports carry Kalibr or Zircon missiles that could reach Florida. A launch from a ship or submarine farther out in the Atlantic or Gulf of Mexico is also physically possible. The aircraft was a tracked civilian flight from Austin with ATC communications describing ice, - @tcheltchy
