Engine Fire Contributes to Miami Crash

Braniff Airways Flight 971, a Douglas DC-7C, crashed approximately three miles west-northwest of the Miami, Fla., International Airport, Mar. 25, 1958, at 0006.1 The accident occurred at night under VFR conditions less than two minutes after takeoff from runway 27R.

AVIONICS

Adaptive Autopilots Have Space Future

Dayton—Many different techniques for designing self-adapting flight control systems that continuously monitor their own performance under changing flight environment and automatically adjust for optimum performance already have been developed despite the newness of the entire concept.

20 Million Lb. Thrust Engine Foreseen

New York—First 1.5-million lb. thrust liquid propellant booster, which will be a cluster of existing rocket engine components, is expected to be ready for testing within a year and to be launched before 1962. After this, following a normal course of development, will come the singlechamber liquid booster in the 1-1.5million lb. thrust class.

Northwest Cuts Overhead, Boosts Profits

Minneapolis—Hard hitting sales tactics and a tight grip on the purse strings have been blended by Northwest Orient Airlines into a profit formula that has propelled the carrier from the status of a $3 million subsidy collector only four years ago to a $5.5 million profit in 1958.

AERONAUTICAL ENGINEERING

Soviets Design Adjustable Landing Gear

Washington—Pilots of certain Russian high-performance aircraft apparently control the angle of attack during takeoff ground roll by varying the length of the landing gear struts since the horizontal tail is ineffective. This arrangement is used to overcome the ground roll longitudinal control problem on some thin-winged aircraft that must use quadricycle landing gear and house the main wheels in the fuselage with small outrigger wheels under the wings.

Azusa Is Precise Aid for Range Safety

San Diego—An electronic watcher which tells the range safety officer exactly where a ballistic missile would land if its power failed completely, and predicts where the nose cone will fall after a normal flight, is contributing to development proving at Air Force Missile Test Center, Patrick Air Force Base, Fla.
