Got lucky again Don?

What about the October 12th attack on the USS Cole Don?

"On November 3, 2002, the CIA fired a AGM-114 Hellfire missile from a Predator UAV at a vehicle carrying Abu Ali al-Harithi, a suspected planner of the bombing plot. Also in the vehicle was Ahmed Hijazi, a U.S. citizen. Both were killed. This operation was carried out on Yemeni soil.

On September 29, 2004, a Yemeni judge sentenced Abd al-Rahim al-Nashiri and Jamal al-Badawi to death for their roles in the bombing. Al-Nashiri, believed to be the operation's mastermind, is currently being held by the U.S. at Guantanamo Bay detention camp. Al-Badawi, in Yemeni custody, denounced the verdict as "an American one." Four others were sentenced to prison terms of five to 10 years for their involvement, including one Yemeni who had videotaped the attack.

On February 3, 2006, 23 suspected or convicted Al-Qaeda members escaped from jail in Yemen. This number included 13 who were convicted of the USS Cole bombings and the bombing of the French tanker Limburg in 2002. Among those who reportedly escaped was Al-Badawi. Al-Qaeda's Yemeni number two Abu Assem al-Ahdal may also be among those now on the loose.

On October 17, 2007, al-Badawi surrendered to Yemeni authorities as part of an agreement with al-Qaeda militants. Following his surrender, Yemeni authorities released him in return for a pledge not to engage in any violent or al-Qaeda-related activity, despite a $5 million reward for his capture. Two other escapees remained at large."

Another fluke eh Don?
