The sheer volume of flames and smoke pouring from the Austin office building where a suicidal pilot slammed his plane at full speed has prompted authorities to investigate whether he had some kind of explosive on board.
Joe Stack, 53, topped off his single engine Piper Cherokee with fuel before crashing into the IRS offices in a kamikaze mission designed to punish the government he believed wronged him.
The full tank of fuel is believed to have contributed to the force of the explosion and subsequent fire, which investigators believe was probably a deliberate tactic by Stack. Investigators are also trying to determine whether Stack had explosives on board with him, sources told ABC News.
