Machines are built to stand immense pressure on the under side of the wings. In some acrobatic manoeuvres I was trying the other day, I made mistakes and caused the machine to stall and then fall in such a way that the full weight was supported by the _upper surface_--by the wires which in most machines are supposed merely to support the weight of the wings when the machine is on the ground. Yes, the Spad is a well built machine, the nearest thing to perfection in point of strength, speed and climbing power I’ve seen yet. Of course it’s heavy and that’s why they put 150-230 HP in them. The other school, that of a light machine with a light motor--depending for its success on lack of weight rather than excess of power, may supplant the heavier machine in time--I can’t tell. So, as anyone who knows has said right along, there is a long way to go in the development of the J N or even the little tri-plane, before American built planes get to the front. Of the bombing game, I don’t know anything at all. Yesterday there was a _revue_ here in honor of Guynemer, and decorations for the pilots of the group who had won them. Three Americans received the Croix de Guerre--members of the Lafayette Escadrille. Lufberry, the American ace, carried the American flag presented to the _escadrille_ by Mrs. McAdoo and the employees of the Treasury Department--besides the two aviation emblems of France. He was called to receive his decoration “for having in the course of one day held seven combats, descended one German plane in flames, and forced five others to land behind their lines” (which means that he is officially credited with one, his thirteenth, and that the other five though probably brought down, do not count for him because there were not the necessary witnesses required by the French regulation). Being the bearer of the flag, he was a very worried man to know what to do with the flag when he should go up to get his medal, till one of the fellows in 124 (the Lafayette) came to his rescue.
