NASA's 99.7-foot-long test jet traveled from California to the Kennedy Space Center while being escorted by an F-15, an F/A-18, and a Gulfstream C-20. Across 41 test flights completed within twelve months, the aircraft achieved speeds up to Mach 1.53 and altitudes of 56,000 feet. The unique design features an elongated nose, a top-mounted engine to redirect sound, and an external vision camera system instead of a standard windshield. These quiet-boom innovations will soon be tested over American communities to capture public noise response data for aviation regulators.

NASA’s pencil-thin X-59 experimental supersonic jet was captured flying over the United States on Wednesday, exactly one year after its maiden flight, as the aircraft began a cross-country journey from California to Florida.
Videos of the distinctive aircraft have since surfaced on social media, drawing attention to the milestone. NASA Administrator Jared Isaacman responded to one such video on X, writing: “Great catch... X-59 making her way to @NASAKennedy”.
The aircraft was en route to NASA’s Kennedy Space Center in Florida when it was spotted by people across the US. Videos of the unusual-looking jet were subsequently widely shared on X, drawing attention to its distinctive pencil-thin design. Its journey comes as the space agency marks a year of flight testing for the experimental aircraft, which is the centrepiece of its Quesst mission.
The aircraft traveled escorted by an F-15, an F/A-18 and a Gulfstream C-20.
NASA Aeronautics also marked the anniversary in a post on X, saying, “One year. New heights. Faster speeds. Since its first flight on Oct. 28, 2025, NASA's X-59 has continued pushing the boundaries of…
Criminals routinely pair compromised birth dates with stolen names, addresses, and phone numbers to assemble comprehensive profiles for identity fraud. These aggregated dossiers allow bad actors to convincingly impersonate victims at corporate help desks or pose as legitimate financial institutions during phishing calls. Cybersecurity specialists recommend withholding real birth dates from retail accounts to disrupt this profiling pipeline.
Engineers engineered an interactive homepage tribute to mark the arcade icon's 30th anniversary, adapting the original game board into the company logo using HTML and CSS. However, an automated gameplay feature designed to kick in after 10 seconds of inactivity led to widespread confusion and unintended noise. The unexpected audio disturbances were ultimately traced to background link-previewing extensions silently triggering the hidden game.
Builders and machinists can access an archive of 45 miniature propulsion designs spread across two catalog pages. The open-access blueprints document decades of miniature aviation engineering, spanning diesel, glow, and spark mechanisms. This technical repository serves hobbyists seeking to fabricate historical and modern powerplants from verified mechanical drawings.
