Blair was in command at USPACOM 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 the death of a Chinese crewmember and the emergency landing of the EP-3. Following the landing, the 24 U.S. crewmen aboard were detained in China for 10 days. The so-called Hainan Island incident threatened to escalate already tense relations between the United States and China. Blair played in a key role in managing the crisis.
