According to a report by Japan's Kyodo News Agency, in the early morning of the 4th, the flight routes of two planes crossed at Haneda Airport in Tokyo, Japan, and a dangerous approach occurred in the air. The anti-collision system of one of the planes issued an alarm. The report said that at around 5:44 local time, when Japan's ANA flight 968 was preparing to land at Haneda Airport, the aircraft's anti-collision system issued an alarm, and the pilot took a climbing operation to avoid the collision. At the time of the incident, an inspection plane from Japan's Ministry of Land, Infrastructure, Transport and Tourism, which had just taken off, was flying nearby. The main task of inspecting an aircraft is to verify the operation status of facilities such as radio and radar systems on the ground from the air. The report quoted information from the Ministry of Land, Infrastructure, Transport and Tourism and others as saying that both planes were flying on routes approved by air traffic controllers, but the inspection plane crossed the route where the All Nippon Airliner descended and landed. The All Nippon Airways passenger plane mentioned above landed after 6:00 local time. None of the 197 passengers and crew on board were injured.
