Last week I was cruising amazon.com and discovered "Jane's Fighting Aircraft of World War I" for a mere $12.00 and at that price I could not pass it up. It arrived today. I had assumed it to be a modern book with colored illustrations, but, not so. It'a a facsimile edition of the original 1919 edition, supplemented with material from the earlier editions of 1914, 1916, 1917, and 1918. (there was no 1915 edition) Thus, it's all black & white, large format (10" x 12.5"), and, large format notwithstanding, the type is incredibly small. (6pt.?) It would be hard going even if I had my teen-age eyeballs back. But more good information about more odd aircraft than I've ever seen. A whole section on engines alone, with blueprint drawings, photos and cut-away drawings. And unexpected trivia like what the mountings looked like for MG's that fired downward through the floor. (Strafing trenches?) Oh, and the engine is an Austro-Daimler 200hp.
