By means of this weapon, daring men, with the true fighting spirit, have already obtained innumerable successes of the greatest importance on all fronts. These results could not have been achieved but for the conviction that German scientists, and engineers had so perfected the design of this divebomber that it could withstand the exceptional demands made on it—especially on the engine and airscrew.
