Photographed October, 1915
In the repair shop of the U. S. Aviation School at North Island the motors are given a gruelling test, being run twenty-four consecutive hours at a speed greater than that given them in actual practice. After this run they are taken down and each part is spread out on a large drawing-table and is subjected to close scrutiny so as to show any defect. Several airplanes as well as seaplanes have been reconstructed in this shop.
