2. During unflared-landing crashes greater fuselage crushing will
occur with high-wing than with low-wing airplanes.
3. Airplanes with strong fuselage structures that do not deform and
produce sharp, well-supported plowing edges will have relatively low
longitudinal acceleration during crashes similar to those studied.
4. Normal accelerations are greatest near the point of impact of the
airplane with the ground.
5. Normal accelerations exceeding human tolerance without injury can
occur in crashes in which modest fuselage damage occurs.
6. The configuration of the airplane had little effect on the normal
accelerations measured in this study.
