While climbing through 29,000 feet, an overheated tire exploded in the wheel well after takeoff and damaged the hydraulic and electrical systems of the aircraft. The plane lost control and crashed. The tire had been serviced with air rather than nitrogen. The air, under high temperature and pressure, resulted in a chemical reaction within the tire itself which led to a explosion of the tire.
