"I grew up wanting to fly," says Graham Bowen-Davies. "I guess I just settled for being an engineer."

He's standing on an indoor track in southern Maryland, watching a giant helicopter take flight. At the end of each of its four spindly arms — arms he helped design and build — a giant rotor churns the air. In the cockpit sits the engine: a 0.7-horsepower, 135-pound graduate student named Kyle Gluesenkamp.

Gluesenkamp is pedaling like crazy to keep the rotors spinning and the craft aloft.

From now until November, President Barack Obama and GOP presidential candidate Mitt Romney will emphasize their differences. But the two men's lives actually coincide in a striking number of ways. In this installment of NPR's "Parallel Lives" series, a look at Romney's time at Cranbrook, an all-boys prep school in Michigan.

Gen. John D. Lavelle commanded the Seventh Air Force during the Vietnam War. He served five steps down the chain of command from President Nixon. In his oral history — recorded by an Air Force history officer in 1978 — he explained how, six years earlier, his life changed forever.

It started with a meeting with a Thai general, Dawee Chullasapya, who had charged Lavelle with overseeing an operation to destroy anti-aircraft guns in North Vietnam. It was a mission necessary to keep Thailand in the war.

The race for the Republican nomination of 1860 was one of the great political contests of American history. It was Abraham Lincoln versus Salmon Chase, versus William Seward.

Author Walter Stahr spoke with Weekends All Things Considered host Guy Raz about his new biography, Seward: Lincoln's Indispensable Man. He describes how a man who was Lincoln's fiercest and most critical opponent eventually became his most loyal and trusted adviser.
