I was driving down the highway at 65 mph and suddenly I saw a flash out of the corner of my eye over my head followed by a tremendous "boom" above me. The sunroof then disintegrated into many sharp shards and rained around the driver and passenger getting into the shifting mechanism, electric seats, seatbelt connectors and all over the passengers. There was no impact and the sunroof blew up and outwards from the inside of the car.
