I am currently reading the book Black Cat 2-1 by Bob Ford, Huey helicopter Air Commander in Vietnam. It is amazing!
“Lieutenant Bob Ford’s spellbinding account of his time as a helicopter pilot during the Vietnam War weaves a tale of courage, love, loss, and hope. Through vivid first-hand accounts, Black Cat 2-1 tells the story of a war that silenced the voices of 2,197 helicopter pilots and 2,717 crew members who were killed in battle”.
