I have written three books about helicopters in Vietnam. Undaunted Valor, An Assault Helicopter Unit in Vietnam; Undaunted Valor, Medal of Honor and Undaunted Valor Lam Son 719. I am researching for a fourth book, Undaunted Valor, Easter Offensive. Each book is based upon events that occurred and presented in the order that they occurred although the books are written as historical fiction. It was suggested that I contact your organization and I might be able to find some that flew in the Easter Offensive of 72. If there are any that did, in any capacity, pilot, crew chief, door gunner, please contact me at mattjacksonbooks@gmail.com or call 931-624-1290 and leave a message. Thanks.
