On a July afternoon, two aircraft—Bashkirian Airlines Flight 2937, a Tupolev Tu-154, and DHL Flight 611, a Boeing 757—collided mid-air over Überlingen, a town in southern Germany. Flight 2937 was carrying 60 passengers and crew, primarily Russian citizens, who were flying from Moscow to Barcelona. Meanwhile, Flight 611, a cargo flight, was en route from Bergamo, Italy, to Brussels, carrying no passengers and just crew members. The collision occurred due to a series of miscommunications and procedural errors involving air traffic control, which resulted in a critical error in altitude separation.The aircraft collided at approximately 35,000 feet, creating a significant disaster that shocked many across the globe. Witnesses described seeing the aftermath of the crash as debris rained down over a residential area, marking a point of fear for local residents. Investigations revealed that the air traffic control was overwhelmed, and crucial information was miscommunicated, leading to both aircraft being in the same airspace at the same altitude. The impact resulted in debris scattering across Lake Constance and the surrounding area, necessitating extensive recovery operations. In total, all 71 souls on board both planes perished in the collision, prompting international discussions about air traffic safety.
