Three interesting and informative aviation articles:
• THE SLOAN BICURVE - At a time when the basic elements of aircraft design were still being sorted out, this forgotten airplane sported a different sort of wing. - Robert Guttman - Aviation History Magazine, 2010 - 2 pages, 3 images.
• THE GUPPY FAMILY - Although the rotund shape of the Guppy transports is known around the world, the entire fleet amounted to only six aircraft and their flying days may be over. - Owen Gault - Air Classics Magazine, 1974 - 7 pages, 16 images. Half of the first-page image is missing, but no text (image 4).
• AMELIA EARHART - Flying made famous, disappearing made her legendary. - by Virgina Morell, photographs by Sarah Leen - 24 pages, 24 images.
All the articles are complete, with minimal wear and age tinting.
