Puzzles involving Charles Lindbergh, American U2 pilot Francis Gary Powers and Geronimo are investigated. Two New Jersey brothers suspect that their uncle built the Spirit of St. Louis's Wright Whirlwind J-5C engine. A used toolbox bought by a Kansas City man contains two pins that could be “poison pins” similar to the one Powers had with him when he was shot down over the Soviet Union in 1960. And a Kentucky woman has a photo she thinks depicts the Apache warrior.
