American fighter-bombers had been in theatre flying combat sorties since 1961, and the U.S. had many experienced pilots from the Korean War and World War II, such as World War II veteran Robin Olds. Untried MiGs and pilots of the VPAF would be pitted against some of the most combat experienced airmen of the U.S. Air Force (USAF) and U.S. Navy. On 3 April 1965 six MiGs took off from Noi Bai Air Base in two groups of two and four respectively, with the first acting as bait and the second being the shooters. Their target were U.S. Navy aircraft supporting an USAF 80-aircraft strike package trying to knock out the Thanh Hóa Bridge. The MiG-17 leader, Lt. Pham Ngoc Lan, attacked a group of Vought F-8 Crusaders of VF-211 from and damaged an F-8E flown by Lt. Cdr. Spence Thomas, who managed to land the aircraft at Da Nang Air Base. A second F-8 was claimed by his wingman Phan Van Tuc, but this is not corroborated by USN loss listings.
