He said he was left with only one shoe because he gave his other shoe-bomb in early December 2001 to some Malaysian men who wanted to blow open a plane's cockpit door and carry out a Sept. 11-style hijacking of their own. Afterward, he flew from Pakistan to Holland and then on to Great Britain.
"I was wearing the shoe," he said, referring to the shoe bomb.
Prosecutors are using the 34-year-old Badat's testimony to show Abu Ghaith played a pivotal role with al-Qaida when he warned Americans "the storm of aircrafts will not stop" on videotapes widely distributed after the Sept. 11 attacks.
Abu Ghaith could face life in prison if he is convicted of conspiring to kill Americans and providing material support to al-Qaida. He is the highest-ranking al-Qaida figure to face trial on U.S. soil since 9/11.
Badat described enthusiasm among al-Qaida recruits after the Sept. 11 attacks.
At one point on cross examination, he was asked about a moment after Sept. 11 when he and others laughed as professed mastermind Khalid Sheik Mohammed crossed the World Trade Center's twin towers off a list of the world's tallest buildings.
"Three thousand plus Americans dead was humorous to you?" defense attorney Stanley Cohen asked.
"Unfortunately, yes," he said with a sheepish expression.
Badat said his eagerness to carry out a suicide mission following more than three years with al-Qaida operatives in Afghanistan wilted when he visited his parents in Gloucester, England, in December 2001 and they asked what he'd done in Afghanistan.
"You'd better not be one of those sleepers," Badat said his father told him.
His mother warned that she "wouldn't want my son to be one of those sleepers," he recalled.
"It was then I decided to back out of the mission," Badat said in testimony from London shown on video screens in a Manhattan courtroom.
Badat, wearing a gray suit with a narrow black tie, sat across from Assistant U.S. Attorney Nicholas Lewin and Cohen as he recalled being asked in late September or October 2001 whether he'd be willing to carry out a suicide attack.
He said bin Laden met with him soon afterward, telling him that the American economy was like a chain.
"If you break one link, you'll bring down the American economy," Badat said bin Laden told him. He said al-Qaida's leader also described sections of the Quran to read if he got scared.
