Why is "1996 Charkhi Dadri mid-air collision" trending?

Wikipedia Overview

On 12 November 1996, Saudia Flight 763, a Boeing 747 en route from Delhi, India, to Jeddah, with a stopover in Dhahran, Saudi Arabia, and Kazakhstan Airlines Flight 1907, an Ilyushin Il-76 en route from Chimkent, Kazakhstan, to Delhi, collided over the city of Charkhi Dadri, around 100 km west of Delhi. The crash killed all 349 people on board both planes, making it the world's deadliest mid-air collision, the deadliest aviation accident without survivors, and the deadliest aviation accident ever in India. The final report from the investigation revealed that the Kazakh crew's failure to maintain the correct altitude led to the collision. Contributing factors included the poor English language skills in the Kazakh cockpit, resulting in inadequate interpretation of directions provided by air traffic control, and three specific incidents of failures in crew resource management (CRM) by the Kazakh crew. The investigators noted the Indian airport lacked a secondary surveillance radar; the airport only had a primary radar, which produced readings of distance and bearing, but not altitude. The report also suggested technical enhancements that would provide assistance in preventing a future crew's mistakes from being allowed to go unchecked in real time.
