When we visited Hanoi, we came across the monument for John McCain.
The monument reads;
On October 26, 1967 in Truc Bach Lake, the people and military of Hanoi captured alive U.S. Air Force pilot John Sney Macan, whose A-4 jet was shot down onto Yen Phu electric plant.
A small correction was that McCain flew for the Navy, not the Air Force. Notwithstanding the ethics of the war, he was a hero. Even if he was captured.
