Robert Ripley's obsession with the odd and keen eye for the curious made him one of the most successful men in America during the Great Depression. Over three decades, his Believe It or Not! franchise grew into an entertainment empire, expanding from newspapers to radio, film and, ultimately, television. Americans not only loved his bizarre fare, but were fascinated by the man himself, and the eccentric, globetrotting playboy became an unlikely national celebrity. This is the story of the man who popularized the iconic phrase, and proof of why we still can’t resist his challenge to “Believe it — or not!”

Throughout the 1800s, the disease struck America with a vengeance, ravaging communities and touching the lives of almost every family. The battle against the deadly bacteria had a profound and lasting impact on America. It shaped medical and scientific pursuits, social habits, economic development, western expansion, and government policy. Yet both the disease and its impact are poorly understood; in the words of one writer, tuberculosis is our "forgotten plague."

The North Vietnamese Army was nearing Saigon and the South Vietnamese resistance was at a low. Nearly 5,000 Americans still needed to remove from South Vietnam, but their South Vietnamese allies, co-workers and friends would be captured by the North Army if they where left behind.
