Last week it was disclosed that the Air Force has suspended low-level testing of the B-1B. The Strategic Air Command has restricted the 72 operational bombers to altitudes of several thousand feet until the crash investigation is complete and safety changes are made on the troubled, and vulnerable, plane...

The bright, low-level stratocumulus clouds reflect 60% of incoming solar rays. But long, thin monsoon clouds let solar heat in while preventing infrared radiation from escaping...
...enrolling as an economics major at the National Autonomous University of Mexico in 1966.
