HOUSTON - Turning an important corner in its three-month-old investigation, the board investigating the Columbia disaster Tuesday said it has settled on a detailed "working scenario" of what went wrong to destroy the space shuttle and kill its crew.
After sifting through a mountain of evidence from the wreckage, telemetry, data from an onboard recorder, photography, wind tunnel testing and complex analyses of aerodynamic and thermal factors, the board said the disaster began with a debris strike against the left wing during liftoff. It ended Feb. 1 as superhot gases poured through a hole in the leading edge and ate into the framework of the left wing until the shuttle ripped apart 240,000 feet over Texas.National Guard aids tornado-torn town
PIERCE CITY, Mo. - National Guardsmen bound for Iraq returned instead to their tornado-flattened hometown of Pierce City to help clean up splintered homes and businesses and check on their loved ones Tuesday after twisters killed at least 40 people in three states.
One person was still listed as missing Tuesday in this southwestern Missouri town.
The death toll reached 18 in Missouri with the discovery of a child's body outside Pierce City, and rose to 15 in Tennessee after a man was found dead in a field near Jackson. The storms Sunday night also were blamed for at least seven deaths in Kansas.
Severe weather returned to Kansas and Missouri Tuesday afternoon, as the National Weather Service issued tornado warnings for 14 counties. There were several reports of tornadoes and some minor damage but no injuries from the new batch of storms.
President Bush on Tuesday issued federal disaster declarations for seven counties in Kansas and 39 in Missouri, an action that allows federal emergency assistance to flow to the affected areas.Suicide note will aid arsenic investigation
PORTLAND, Maine - The man authorities say was involved in the arsenic poisonings of northern Maine churchgoers killed himself and left a suicide note that contained "important information," a police spokesman said Tuesday.Daniel Bondeson's note has prompted police to continue their investigation into the poisoned coffee that killed one parishioner and sickened 15 others at Gustav Adolph Lutheran Church in New Sweden, state police spokesman Stephen McCausland said. At least three people remained in critical condition Tuesday at a Bangor hospital.
State police have said that Bondeson, a potato farmer, was involved, but may not have acted alone in spiking the coffee. Internal church squabbling is part of their investigation into the motive for the April 27 poisonings.Elsewhere . . .
