Do public libraries still have books like "Hatcher's Notebook"?  My working copy is a 3rd (1962)edition.  I bought it mail order from Ray Riling in late 1962.  I rented a PO Box in Ewa, Hawaii because Riling would not or could not guarantee delivery to a military address. I read it cover-to-cover sitting in one of those cargo-strap seats in a GV-1 flying from Guam to Hickam to El Toro with a stop at every little island between Guam & Hickam.  About 18 hours flying time and 4 or 5 more on the ground.  Too slow to get jet lagged.  I was just worn out.
