During this time, there were 120 accidents caused by spatial disorientation which were responsible for 37 fatalities and 56 disabling injuries. Major causal factors are analyzed and recommendations made for changes in aircrew training, education and aircraft instrumentation. Also discussed are the effects of operations undertaken in hostile environments.
