HISTORY DETECTIVES host Elyse Luray pilots an airplane to relive the memory of one of America's first, and youngest, barnstormers. Pilot "Cromwell Dixon" lost his life at 19 when his airplane crashed. Then, details in "Bartlett's Sketchbook" suggest the scenes illustrate the first ever US-Mexican border survey. Host Eduardo Pagan wonders whether the sketchbook made that journey, and if it belonged to Bartlett? Finally, a dumpster find may be a jazz history treasure. In the encore segment, Tukufu Zuberi sets out to find whether these metal "Duke Ellington Plates" printed the first copy of the Ellington hit, Take the A Train.
