After a few days at St. Omer we received our machines, which were Moranes of three different types: “A” Flight had Morane “bullets,” 80 h.p.; “B” Flight, 110 h.p. Morane biplanes; and “C” Flight, Morane “parasols.”
Of the “parasol,” a two-seater monoplane, it is unnecessary to say very much, as they were soon replaced by “bullets,” and “C” Flight did practically no work on them. The machine is best, perhaps, described as a biplane without any bottom planes, by which is meant that the wings were above the pilot’s head, a feature which suggested its nickname. It had an 80 h.p. Le Rhone at that time, almost the best air-cooled rotary engine. They were good for artillery registration, as the view downward was excellent; they were very stable also, easy to fly and to land, and, in fact, were “kind” machines, giving their pilots the sort of feeling afforded by a good-tempered, confidential old hunter.
The Morane biplane had a more powerful engine, the 110 Le Rhone, also an air-cooled rotary, and was quite an efficient “kite,” as the R.F.C. called them, with its inveterate habit of inventing pet names for its aeroplanes. It was draughty and cold to sit in, but was light on the controls and had a reasonably good performance. This machine was also a two-seater, like the “parasol,” with the observer’s seat behind the pilot’s.

The Morane “bullet,” with a 80 h.p. Le Rhone engine, was quite a different proposition.
This was a monoplane with a fuselage (body) of the monococque, or cigar-shaped, type and very small wings, giving, therefore, a very high loading per square foot of lifting surface. The speed near the ground was not too bad for 1916, being about ninety to ninety-five miles per hour, but, owing to the high loading on the wings, the machine became inefficient at a height. It had the gliding angle of a brick, as a pilot moodily complained after an unsuccessful forced landing. It is obvious that, if a machine has a very small wing surface, it must be kept going fast, when gliding without the engine, to preserve its flying speed, and this can only be done by keeping the nose well down; hence the unfriendly description quoted above.
