Pilot angry at IRS, crashes plane into tax agency office

A disgruntled software engineer Joseph Andrew Stack, who was furious at the US Internal Revenue Service (IRS), crashed his small plane into the building in Austin, Texas housing nearly 200 federal tax employees, igniting a raging fire that sent workers running for their lives.

The suicide attack left one person dead and 13 injured inside the Austin building. Stack, 53, who crashed the Piper Dakota into the building, was also confirmed dead.

The incident was described as an intentional assault on a US government institution, but authorities have said the crash did not appear to have any terror links.

Fighter jets scrambled over the building following the incident that brought back shocking memories of the 11th September, 2001 terror attacks.
