Business News The last words of Joe Stack | Page 2

A software engineer furious with the Internal Revenue Service launched a suicide attack on the agency Thursday by crashing his small plane into an office building containing nearly 200 IRS employees, setting off a raging fire that sent workers running for their lives.

At least one person in the building was missing.

The FBI tentatively identified the pilot as Joseph A. Stack, 53. Law enforcement officials, speaking on condition of anonymity because the investigation was still going on, said that before taking off, Stack apparently set fire to his house and posted a long anti-government screed on the Web. It was dated Thursday and signed "Joe Stack (1956-2010)."

In it, the author cited run-ins he had with the IRS and ranted about the tax agency, government bailouts and corporate America's "thugs and plunderers."

The pilot took off in a four-seat, single engineer Piper PA-28 from an airport in Georgetown, about 30 miles from Austin, without filing a flight plan. He flew low over the Austin skyline before plowing into the side of the hulking, seven-story, black-glass building just before 10 a.m. with a thunderous explosion that instantly stirred memories of Sept. 11
