In court documents filed this week in U.S. District Court in Manhattan, aviation companies are seeking to force five FBI employees to provide testimony that may help defend against claims the companies share blame in the attacks.
"The aviation parties anticipate that the FBI witnesses' testimony will demonstrate that the FBI had information before Sept. 11 indicating that al-Qaida may have been about to launch terrorist attacks on civil aviation, which it did not timely pass along to the Federal Aviation Administration," lawyers wrote.
