"We got calls from three different U.S. groups just today," Costanzo said. Those investors want the company to relocate, which would incur significant costs and downtime, but the company is ready to go if that's what it takes. Symphony recently announced a deal with Spartan School of Aeronautics to provide a fleet of about 40 training aircraft. "Spartan understands our situation, and they are standing by us," Costanzo said. "They'll give us some time to get it solved, but we know they won't wait forever." Meanwhile, the company is moving forward with plans to have a strong marketing presence at AirVenture 2006, coming up in just a few weeks. "We'll be there in full force, and might have some positive updates for you then," Costanzo said. An all-glass version of the 160 is nearing certification, and a diesel version and a four-seater are in the works.
