According to a report by Flight Global, USAF officials believe brownout conditions caused the April 8 crash of a CV-22 Osprey tilt-rotor aircraft that killed four, two Air Force Special Operations Command airmen, a US soldier, and a civilian. Flight Global attributes the information to “a source familiar with preliminary findings of the US military investigation.” DARPA and the services have been working for several years on varied solutions to the problem of brownout, the term used to describe a greatly reduced visibility condition often caused by rotary wing aircraft in desert-like terrain.
