The article reports Larsen said Foster City hopes to challenge the assertion in court by San Francisco airport director John Martin that federal law limits his powers over flight routes.

Foster City hopes to present the Roundtable with a legal brief later this year supporting the position that Martin has more regulatory power.Aug 31,  · I am using Pettit's EasyPoxy topside paint as bottom paint.
