FLT CREW OF B737-800 TAKES OFF WITH FLAPS UP.

Narrative

WE PUSHED BACK FROM THE GATE AND I INSTRUCTED THE FO TO START BOTH ENGS; ANTICIPATING A SHORT TAXI. WE PERFORMED THE AFTER START CHKLIST AND THE FO CALLED FOR TAXI. AS WE STARTED THE TAXI; I CALLED FOR THE TAXI CHKLIST; BUT IMMEDIATELY BECAME CONFUSED ABOUT THE RTE AND QUERIED THE FO TO HELP ME CLEAR UP THE DISCREPANCY. WE DISCUSSED THE RTE AND CONTINUED THE TAXI. WE WERE CLRED TO CROSS RWY 4; AND I ASKED THE FO TO SIT THE FLT ATTENDANTS. HE MADE THE APPROPRIATE PA. WE WERE CLRED FOR TKOF RWY 1; BUT THE FLT ATTENDANT CALL CHIME WASN'T WORKING. I HAD CALLED FOR THE BEFORE TKOF CHKLIST; BUT THIS WAS INTERRUPTED BY THE COMS GLITCH. AFTER AFFIRMING THE FLT ATTENDANTS READY; WE VERBALLY CONFIRMED BEFORE TKOF CHKLIST COMPLETE. ON TKOF; ROTATION AND LIFTOFF WERE SLUGGISH. AT 100-150 FT AS I CONTINUED TO ROTATE; WE GOT THE STICK SHAKER. THE FO NOTICED THE NO FLAP CONDITION AND PLACED THE FLAPS TO 5 DEGS. THE REST OF THE FLT WAS UNEVENTFUL. WE WROTE UP THE TKOF WARNING HORN BUT FOUND THE CIRCUIT BREAKER POPPED AT THE GATE. THE CAUSE OF THIS POTENTIALLY DANGEROUS SIT WAS A BREAKDOWN IN CHKLIST DISCIPLINE ATTRIBUTABLE TO COCKPIT DISTR. THE TAXI CHKLIST WAS INTERRUPTED BY MY TAXI RTE CONFUSION. THE BEFORE TKOF CHKLIST WAS INTERRUPTED BY A FLT ATTENDANT COM PROB. AND FOR SOME REASON; THE TKOF WARNING HORN CIRCUIT BREAKER POPPED; REMOVING THE LAST CHK ON THIS TYPE OF THING. BOTH OF US FEEL OURSELVES TO BE HIGHLY DILIGENT PROFESSIONALS. WE GOT OURSELVES IN A BOX BY ALLOWING OURSELVES TO BE DISTR FROM THE CHKLIST. FROM NOW ON; IF I AM INTERRUPTED WHILE PERFORMING A CHKLIST; I INTEND TO DO THE WHOLE THING OVER AGAIN.
