Narrative:
Returning from a training flight; the pilot flying opened the right window. Immediately after opening the window; the window began to rapidly oscillate because one of the hinges on the top of the window broke. The pilot attempted to close the window and was unable to close it before it broke off the other hinge. As the window flew back with the wind; it hit the side of the aircraft and broke another fixed window on the right side of the plane. The window also struck the outside edge of the right horizontal stabilizer creating a dent in the surface. The window departed the aircraft approximately 7 nautical miles west of the ZZZ airport on the 275 degree radial from the ZZZ VOR. The aircraft was traveling approximately 115 knots when the window broke off. The flight was using 'flight following' with approach.
