NASA researchers set up to run volcanic ash through an F117 engine mounted on a C-17 cargo transport at Edwards Air Force base in California. Ground testing of improved sensors could identify changes in vibration, speed, temperature and emissions that are symptomatic of engine problems before they become serious safety concerns.
