Narrative:
On takeoff, captain's window is found not to be locked closed. Takeoff was continued, xfer of control from captain to first officer. Window closed in the air between 500-1000 ft. At 7000 ft, control xfer back to captain. Checking the window locked is a checklist item which we did and I read back 'locked' and even verified the handle stowed (it was stowed in the unlock rather than locked position). I looked up at the indicator and thought it said closed, but obviously it wasn't. I basically saw what I wanted to see. There were some distrs at the time, but none more than usual. Maintenance had taxied the aircraft in and left the window cracked and unlocked so it was not visually opened. I should have been more diligent in catching it. There is a video out showing a B757 taking off with the window open and that was very instrumental in my decision to continue the takeoff instead of aborting. It is a very startling event and can make you react incorrectly. Recommend that we continue to use that video.

Title: A B767 CAPT, DURING DEP FROM LAX, REALIZED HIS COCKPIT WINDOW WAS UNLOCKED BUT CONTINUED THE TKOF ROLL.
Narrative: ON TKOF, CAPT'S WINDOW IS FOUND NOT TO BE LOCKED CLOSED. TKOF WAS CONTINUED, XFER OF CTL FROM CAPT TO FO. WINDOW CLOSED IN THE AIR BTWN 500-1000 FT. AT 7000 FT, CTL XFER BACK TO CAPT. CHKING THE WINDOW LOCKED IS A CHKLIST ITEM WHICH WE DID AND I READ BACK 'LOCKED' AND EVEN VERIFIED THE HANDLE STOWED (IT WAS STOWED IN THE UNLOCK RATHER THAN LOCKED POS). I LOOKED UP AT THE INDICATOR AND THOUGHT IT SAID CLOSED, BUT OBVIOUSLY IT WASN'T. I BASICALLY SAW WHAT I WANTED TO SEE. THERE WERE SOME DISTRS AT THE TIME, BUT NONE MORE THAN USUAL. MAINT HAD TAXIED THE ACFT IN AND LEFT THE WINDOW CRACKED AND UNLOCKED SO IT WAS NOT VISUALLY OPENED. I SHOULD HAVE BEEN MORE DILIGENT IN CATCHING IT. THERE IS A VIDEO OUT SHOWING A B757 TAKING OFF WITH THE WINDOW OPEN AND THAT WAS VERY INSTRUMENTAL IN MY DECISION TO CONTINUE THE TKOF INSTEAD OF ABORTING. IT IS A VERY STARTLING EVENT AND CAN MAKE YOU REACT INCORRECTLY. RECOMMEND THAT WE CONTINUE TO USE THAT VIDEO.
