An EP-3E United States Navy surveillance aircraft collides with a Chinese People's Liberation Army Shenyang J-8 fighter jet. The Navy crew makes an emergency landing in Hainan, China and is detained.

The Hainan Island incident occurred on April 1, 2001, when a United States Navy EP-3E ARIES II signals intelligence aircraft and a People's Liberation Army Navy (PLAN) J-8II interceptor fighter jet collided in mid-air, resulting in an international dispute between the United States and the People's Republic of China (PRC).

The EP-3 was operating about 70 miles (110 km) away from the PRC island province of Hainan, as well as about 100 miles (160 km) away from the Chinese military installation in the Paracel Islands, when it was intercepted by two J-8 fighters. A collision between the EP-3 and one of the J-8s caused a PRC pilot to go missing (later presumed dead); the EP-3 was forced to make an emergency landing on Hainan. The 24 crew members were detained and interrogated by the Chinese authorities until a statement was delivered by the United States government regarding the incident. The exact phrasing of this document was intentionally ambiguous and allowed both countries to save face while defusing a potentially volatile situation between militarily strong regional states.

The Lockheed EP-3 is electronic signals reconnaissance version of the P-3 Orion, operated by the United States Navy.
