A federal judge began listening to testimony Monday that will help him decide whether the owners of the World Trade Center buildings destroyed in the Sept. 11 attacks can pursue billions of dollars in damages from aviation companies linked to the hijacked planes.
The buildings' owners, World Trade Center Properties, have already received nearly $5 billion in insurance proceeds.
Lawyers for the owners argued during opening statements that the money they already have received does not preclude them from separately pursuing damages against aviation companies.
Attorney Roger Podesta, speaking for companies including United Airlines Inc., US Airways Inc., American Airlines Inc. and its parent company, AMR Corp., said the $3.5 billion being sought for destruction of the twin towers and a third skyscraper would amount to double compensation.
