Narrative:

Departing sea runway 16L on bluitt 3 SID turning through 140 degrees going toward F134J, we were given a heading of 160 degrees. We reversed turn to 160 degrees and were holding 160 degrees when the controller asked if we were still flying the bluitt 3 SID. Apparently we read back someone else's clearance and were not corrected. We quickly turned back on the SID and the remainder of departure was uneventful. What struck me the most about this event was neither the flight deck nor the controller were that busy. Although the clearance seemed abnormal, all apprehension was gone after the readback went uncorrected.

Title: A B757 FLT CREW READS BACK AND FOLLOWS DEP CTLR INSTRUCTIONS THAT WERE INTENDED FOR SOMEONE ELSE.

Narrative: DEPARTING SEA RWY 16L ON BLUITT 3 SID TURNING THROUGH 140 DEGS GOING TOWARD F134J, WE WERE GIVEN A HDG OF 160 DEGS. WE REVERSED TURN TO 160 DEGS AND WERE HOLDING 160 DEGS WHEN THE CTLR ASKED IF WE WERE STILL FLYING THE BLUITT 3 SID. APPARENTLY WE READ BACK SOMEONE ELSE'S CLRNC AND WERE NOT CORRECTED. WE QUICKLY TURNED BACK ON THE SID AND THE REMAINDER OF DEP WAS UNEVENTFUL. WHAT STRUCK ME THE MOST ABOUT THIS EVENT WAS NEITHER THE FLT DECK NOR THE CTLR WERE THAT BUSY. ALTHOUGH THE CLRNC SEEMED ABNORMAL, ALL APPREHENSION WAS GONE AFTER THE READBACK WENT UNCORRECTED.
