The fitting was an SAE straight thread and was likely loosened by torque applied to the fueling hose. After the incident, these fittings had additional means applied to restrict loosening, a cover installed to deflect any leakage, and means taken to restrict hose torque by using a different style nozzle. In addition, different fittings have now been deployed.
