21 years ago a Chinese miitary jet collided with a Navy signals intel plane in international waters. The Navy plane had to make an emegency landing on a Chinese island, and the crew was held for 10 days. It was shortly after George W. Bush became president, and this was kind of seen as China testing him. I don’t think Chinese jets get right up close to our jets without the bosses knowing about it in advance. https://www.reuters.com/world/chinese-jet-came-within-20-feet-us-military-aircraft-us-military-2022-12-29/
