The pilot, who died in the blaze, left a note behind espousing violence. It was initially thought he crashed into the building housing the FBI, but that property is located a few units over.

Official: Plane crash pilot left anti-IRS Web note

Thursday, February 18, 2010 - A software engineer furious with the Internal Revenue Service plowed his small plane into an office building housing nearly 200 federal tax employees on Thursday, officials said, setting off a raging fire that sent workers fleeing as thick plumes of black smoke poured into the air.

A U.S. law official identified the pilot as Joseph Stack and said investigators were looking at an anti-government message on the Web linked to him. The Web site outlines problems with the IRS and says violence "is the only answer." ...

"Violence not only is the answer, it is the only answer," the long note on Stack's Web site reads, citing past problems with the tax-collecting agency.

"I saw it written once that the definition of insanity is repeating the same process over and over and expecting the outcome to suddenly be different. I am finally ready to stop this insanity. Well, Mr. Big Brother IRS man, let's try something different; take my pound of flesh and sleep well," the note, dated Thursday, reads.
