Meteorologists Baffled by 50-Mile Wide Radar Anomaly in Midwest
On Dec. 10, a mysterious, 50-mile-wide radar anomaly passed from southeastern Illinois into Kentucky, eventually breaking up after lingering in the air for over 10 hours. The National Weather Service (NWS) and local meteorologists were baffled by the stream, asking the public to report on Twitter if they noticed anything visible in the skies.
The strange anomaly appeared around 3 p.m. CST as a blip on NWS doppler radar just south of Olney, IL, before continuing to expand as it moved south through Indiana and across the Kentucky border. The phenomenon was quickly given the hashtag #tristatewx, with speculation ranging from a flock of birds, to secret military operations, or an explosion of material raining down from space.
The most likely explanation though, is a military countermeasure called chaff, developed during WWII to scramble enemy radar. Doppler radar works by measuring the reflectivity of precipitation in the air, so in order to confuse radar the military realized it could release other types of material, including thin aluminum and metallic glass fibers to allow aircraft to travel undetected.
Aside from the questionable nature of chaff – regarding its environmental safety and the general lack in public knowledge of its use – it’s a common occurrence for meteorologists, who are typically forewarned by the military when it’s released.
In this case however, neither the Air Force nor any other branch took responsibility or gave notice to the National Weather Service that it would release chaff.
What we believe was chaff, released by aircraft this afternoon, has been showing up on radar for the past 10 hours now. Originated south of Olney, IL at 2:50 PM and now is 150 miles SE entering far north TN. pic.twitter.com/BxLQcW2aIh

Unsolved: The Mysterious Disappearance of Santiago Flight 513
On September 4, 1954, Santiago Airlines Flight 513 departed from Aachen, West Germany, destined for Porto Alegre, Brazil. The flight should have taken around 18 hours.
Instead, it took 35 years. On October 12, 1989, without any contact with air traffic controllers, Santiago Flight 513 was spotted circling the Porto Alegre airport, where it eventually made a successful landing. Witnesses at the airport reported an eerie sense of disbelief as the ghostly plane descended, unannounced and seemingly out of nowhere, stirring questions that no one was prepared to answer. How did Santiago Flight 513 disappear so suddenly, only to reappear decades later in such an inexplicable manner?
Flight 513: The Plane That Never Arrived
Santiago Flight 513’s journey began like any other flight from that era. Piloted by Captain Miguel Victor Cury, the aircraft had been checked, cleared, and prepped for its scheduled 18-hour flight from Aachen, Germany, to Porto Alegre, Brazil. The plane, a Lockheed Super Constellation, was known for handling long flights, was in top condition, and had taken similar routes several times in the past.
With 88 passengers and four crew members on board, the plane set off smoothly. Passengers likely settled into the flight, unaware of any unusual circumstances or issues. But somewhere over the Atlantic Ocean, all contact with Santiago Airlines Flight 513 ended without warning. Attempts to reach the crew through radio communications failed, and the sudden silence led to a number of search and rescue operations. Rescue teams searched vast stretches of ocean for days on end, holding out hope for survivors, however, no trace of the aircraft or its passengers could be found. The routine flight had inexplicably vanished, leaving behind only questions.
