Earlier this week, a United Airlines flight experienced a close call with a military Black Hawk helicopter near John Wayne Airport in Southern California. The incident occurred around 8:40 PM when the helicopter, returning from a training mission, crossed into the aircraft's flight path, prompting the pilots of United flight 589 to halt their descent to avoid a collision. According to the FAA, the airplane came within 525 feet vertically and 1,422 feet laterally of the helicopter. This alarming event has triggered calls for an investigation into compliance with new air traffic regulations aimed at ensuring such near misses are avoided. Just over a year ago, an American Airlines jet collided with an Army helicopter near Washington, D.C., killing 67 people and raising concerns about air traffic safety. United Airlines confirmed that their pilots received traffic alerts about the helicopter, and they promptly leveled off the aircraft to maintain a safe distance.
