Narrative:

We were cleared for takeoff and given a turn to 260 degrees. (Takeoff on runway 280). For some reason probably because we had taken off from the same airport earlier in the day, I 'heard' turn to 360 degrees. I took off and started a right turn to 360 degrees and turning through about 310 degrees sensed something was wrong. I asked the first officer if there was a problem and he said the turn was supposed to be left to 260 degrees. I immediately reversed our turn and about that time departure control cleared us direct to our first fix. 2 things disturbed me about this incident. I turned the wrong way through carelessness, inattn, or whatever. The first officer knew I was wrong, but for whatever reason let me do it. 2 recommendations: eternal vigilance, etc and reemphasize the necessity of calling to the other crew members attention any inappropriate action, whether you be the captain or first officer.

Narrative: WE WERE CLRED FOR TKOF AND GIVEN A TURN TO 260 DEGS. (TKOF ON RWY 280). FOR SOME REASON PROBABLY BECAUSE WE HAD TAKEN OFF FROM THE SAME ARPT EARLIER IN THE DAY, I 'HEARD' TURN TO 360 DEGS. I TOOK OFF AND STARTED A R TURN TO 360 DEGS AND TURNING THROUGH ABOUT 310 DEGS SENSED SOMETHING WAS WRONG. I ASKED THE FO IF THERE WAS A PROBLEM AND HE SAID THE TURN WAS SUPPOSED TO BE L TO 260 DEGS. I IMMEDIATELY REVERSED OUR TURN AND ABOUT THAT TIME DEP CTL CLRED US DIRECT TO OUR FIRST FIX. 2 THINGS DISTURBED ME ABOUT THIS INCIDENT. I TURNED THE WRONG WAY THROUGH CARELESSNESS, INATTN, OR WHATEVER. THE FO KNEW I WAS WRONG, BUT FOR WHATEVER REASON LET ME DO IT. 2 RECOMMENDATIONS: ETERNAL VIGILANCE, ETC AND REEMPHASIZE THE NECESSITY OF CALLING TO THE OTHER CREW MEMBERS ATTN ANY INAPPROPRIATE ACTION, WHETHER YOU BE THE CAPT OR FO.
