5. The process of "soaring" would not be possible for a loaded glider and the range or action obtainable is therefore limited to that of a normal glide. From a height of 15,000 feet in still air the machines could glide about fifteen miles. A favourable wind would increase this range, while a head wind would considerably reduce it. 6. In view of its good angle of glide and low landing speed the machine should provide an excellent target for some time before landing. Its flimsy construction would render it and its occupants singularly vulnerable to all kinds of fire.
