Bandmates Shocked by Texas Pilot's Rage

The crazed pilot who launched a kamikaze air attack on a Texas IRS office hid his anger so deeply, friends say they had no idea of his anti-establishment rage or the money woes he said were behind it.

Joseph Stack, 53, had a nice home in middle-class Austin, Texas. He owned a single-engine airplane and had enough money to pursue a passion for country music that led him to produce his own album several years ago, pals told The Post.

"We didn't think he was struggling financially, the way he presented himself. He never aired any grievance. He was real easygoing," said Ric Furley, who played with Stack in an alt-country band.

"He had the airplane. He had a lot of nice musical equipment," said Pam Parker, who managed Stack's band, which was fronted by her husband, Billy Eli.

"There wasn't any indication that we saw that there was any difficulty. It seemed like a very typical sort of suburban life."

Furley and Parker said they were stunned to hear of Stack's Thursday morning air attack and the anti-government suicide screed he posted on the Internet beforehand.

Stack and one other person died in the explosion and fire at the building where 200 IRS employees worked. Thirteen people were injured, one of whom was still in the hospital yesterday with burns.

An official told CNN that Stack may have replaced some of the seats in the plane with a fuel drum order to cause maximum damage.

Investigators were trying to figure out if marriage woes played a part in Stack's attack.

His wife and stepdaughter reportedly spent the night before his attack in a hotel.
