FORT ATKINSON, Wis. — A corporate aircraft apparently broke up in flight and crashed on a wooded ridge Monday, killing all eight people aboard, authorities said.
Witnesses and investigators said the twin-engine turboprop Beechcraft King Air 200 seemed to break apart en route from Chicago to Baraboo, about 150 miles away.
"What we've seen so far is indicative of an in-flight breakup," said Stephen Wilson, a National Transportation Safety Board investigator.
The plane had left Meigs Field in Chicago at 7:51 a.m. and went down half an hour later about five miles northwest of here and about 60 miles short of Baraboo, authorities said.
"The pilot was on his descent toward Baraboo when he radioed, 'Mayday, mayday,' several times," said Mort Edelstein, a Federal Aviation Administration spokesman in Chicago.
