AKRON (Aug. 1)—Goodyear, sole supplier of aircraft tires to Air France for the Concorde supersonic jet since 1995, is sending a two-person technical team at the request of French authorities to join the investigation of the catastrophic July 24 crash of a Concorde just outside Paris. Investigators currently believe that one or more of the eight Goodyear tires on the airplane burst during takeoff, and debris from the tires may have damaged an engine, causing the plane to crash into a hotel. All 109 people aboard and five on the ground were killed. The tires Goodyear supplies are ``regular aircraft tires, suitable for the Concorde,´´ a company spokesman said. The company has no idea how long the Goodyear employees will stay at the site, he added, refusing to identify them.
