A federal judge will soon decide whether the owners of the World Trade Center can make aviation companies pay billions of dollars in damages over the September 11th attacks.
The Trade Center owners say several airlines including American and United, along with Boeing and the Massachusetts Port Authority, were negligent in allowing terrorists to board the planes and crash them into the Twin Towers.
The defendants argue they should not have to pay because the owners have already collected nearly $5 billion in insurance.
The judge has said the owners could potentially get a maximum of $3.5 billion from the defendants.
Arguments are expected to begin Monday and last for three days.
