WASHINGTON _ A device capable of detecting the kind of plastic explosive that officials say destroyed Pan Am Flight 103 went into service Wednesday at Dulles International Airport. James B. Busey, administrator of the Federal Aviation Administration, said the Thermal Neutron Analysis or TNA device represents a "significant improvement in performance" over earlier generations of detection technology. "The machine has the capability of detecting the explosives that we think were present on Pan Am 103," the airliner destroyed over Scotland two years ago, Busey said. The Dulles detector is the fourth to be installed at international airports. Other TNA units are at John F. Kennedy International Airport in New York, the Miami International Airport and Gatwick Airport near London.Teacher identified
as lung donor
PALO ALTO, Calif. _ A Salt Lake City teacher was identified Wednesday as the woman who last week donated one-third of her right lung to her 12-year-old daughter in a pioneering medical operation. Doctors removed a section of lung from 45-year-old Versell Johnson on Oct. 25 and implanted it in her daughter, Mazie Bond. The girl suffered from a lung ailment common in children born prematurely. Dr. Vaughn Starnes, who headed the surgical team, said that the girl may experience some rejection episodes as her body's immune system reacts to the foreign tissue but that he thought the episodes could be controlled with drugs.
