Narrative:

On short final the first officer's sliding window had a flash; followed by severe shattering. Power to the window was de-selected. Control tower was informed; and emergency equipment was sent out as a precaution. Uneventful landing and taxi to gate. Entry was made into the ship's logbook; and maintenance was advised. Mechanic said failure of the windows 'controller' was most likely the cause; allowing too much electrical power to heat the window.
