The plane was just staggering through the air. Any increase in the flying angle would surely send it into a spin. Bill started back toward the cockpit and in his hurry slipped on the smooth laminated wood which protected the wing surface. He caught himself in time to keep from slipping off, but lost several seconds. Once more he started moving back to the cockpit. If he could only make it before the spin started. A DH in a spin takes a considerable altitude to come out. Sometimes they do not come out regardless of the altitude at which they are flying. Bill had a scant two thousand feet when he started to climb out of the cockpit the first time. He had lost some altitude since that.
