Military and civilian researchers will descend upon Grand Forks AFB, N.D., this month to begin a study of the effects of exposure to jet aviation fuel in cold weather. In this first phase of the two-part study, researchers plan to gather data on the level of exposure experienced by airmen during regular work activities. A second phase, set for next year, will focus on the relationship between exposure and health effects, if any.
Expanded production of the B-21 bomber can be accomplished at Northrop Grumman's existing Palmdale, Calif., facilities, the Air Force said. It also said test aircraft will be so simular to the production version that early examples could be used in combat if called for.
