WASHINGTON (AP) — Five families who lost relatives in the 2001 terrorist attacks have settled with the airline industry, saying their negligence lawsuit yielded new information about security lapses, attorneys said Wednesday.

The families refused money from the Victim Compensation Fund, which was created by Congress to protect airlines from a barrage of litigation, so they could pursue the lawsuit and highlight airport security failures.

"We do feel we have the answers we sought," said Julia Shontere, mother of Angela Houtz, a 27-year-old La Plata, Md., resident who worked in the office of naval intelligence at the Pentagon.

Along with Houtz, the Pentagon victims included Gerald Fisher, Ronald Golinski and Ernest Willcher. The family of Sigrid Wiswe, killed in the World Trade Center, settled their case with the airlines but not with the building's owners.

Details of the settlement were not released. It must be approved by U.S. District Judge Alvin K. Hellerstein of the Southern District of New York.
