#911后第二次全美停飞
The nationwide flight halt in the United States may look like it was caused by a sudden “outage” in the air traffic control communications system, but a closer look reveals that a number of long-standing problems all came to a head at once. The immediate trigger was a simultaneous communications failure at every regional air traffic control center—all 22 of them, according to the transportation secretary.
The FBI has ruled out a cyberattack, and the investigation is now focusing on whether a software update was to blame. The outage affected the telecommunications network managed by L3Harris, the line used for communications between air traffic controllers and pilots. On a deeper level, the air traffic control system has long been operating with serious problems: outdated equipment and staff shortages. Congress approved $12.5 billion for upgrades last year, but the transportation secretary himself acknowledged that another $30 billion is needed to complete the overhaul. So this flight halt wasn’t an “accident” so much as a glaring warning light flashing all at once over years of neglected infrastructure.
After the official grounding order was issued, nearly 7,000 flights were delayed or canceled. The grounding disrupted travel for several NBA teams, and it looks like NBA games today may all be delayed. The chaos in air travel this weekend may take a while to clear up.
