## Discrepancy

ABORTED TAKEOFF AFTER PILOTS WINDOW OPENED AT 80-90 KTS.  PILOTS REPORTED WINDOW WAS NOT FULLY LOCKED.  *S/D*  CAPTAIN'S SLIDING WINDOW WAS NOT FULLY LOCKED.  RED-COLORED RELEASE BUTTON ON WINDOW HANDLE POPS UP WHEN THE WINDOW IS LOCKED.  THIS SERVES AS A VISUAL INDICATION.  ENSURING THAT WINDOW IS FULLY CLOSED AND LOCKED PRIOR TO TAKEOFF HAS BEEN AND REMAINS AN ELEMENT OF THE FLIGHT CREW'S PREFLIGHT CHECKLIST.
