Narrative:

Atl tower cleared cessna 210 for takeoff runway 8R to fly initial 020 degree heading. Next, aircraft Z, EMB145 cleared for takeoff to fly 070 degree heading. We were next in line, and cleared for takeoff runway 8R to fly 020 degree heading. I am 100% sure of what I heard. The captain heard 020 degree heading also, and read it back as such. Right after liftoff, tower issued us some taxi instructions relating to runway 8R, to which captain radioed back that we were airborne. Tower realized error, then handed us off to departure. Climbing through about 8500 ft MSL, departure asked us to turn immediately to a 090 degree heading. We complied, and departure asked us what heading tower had assigned us. We replied 020 degrees. He checked with tower, came back and told us tower had us fly 070 degree heading. We said no, to pull the tapes if he had to. He (departure) then turned us to a 330 degree heading and handed us off to center. No TCASII TA's or RA's resulted. Supplemental information from acn 536577: atl tower cleared us for takeoff from runway 8R and turn to a 020 degree heading at the MM. I told departure control to pull the tapes if they didn't believe me. Departure control then told us 'it was no big deal.' (it's a big deal to me if I'm going to hit another aircraft.) I feel that poor visibility was a factor for tower and they just got us out of sequence or mixed up from where they thought we were, which might be the reason they assigned us the wrong departure heading of 020 degrees instead of 070 degrees which they say they assigned us.

Title: AN A320 CREW, DEPARTING ATL, TURNED TO THE WRONG HEADING, REQUIRING CORRECTIVE VECTORS FROM ATC.

Narrative: ATL TWR CLRED CESSNA 210 FOR TKOF RWY 8R TO FLY INITIAL 020 DEG HDG. NEXT, ACFT Z, EMB145 CLRED FOR TKOF TO FLY 070 DEG HDG. WE WERE NEXT IN LINE, AND CLRED FOR TKOF RWY 8R TO FLY 020 DEG HDG. I AM 100% SURE OF WHAT I HEARD. THE CAPT HEARD 020 DEG HDG ALSO, AND READ IT BACK AS SUCH. RIGHT AFTER LIFTOFF, TWR ISSUED US SOME TAXI INSTRUCTIONS RELATING TO RWY 8R, TO WHICH CAPT RADIOED BACK THAT WE WERE AIRBORNE. TWR REALIZED ERROR, THEN HANDED US OFF TO DEP. CLBING THROUGH ABOUT 8500 FT MSL, DEP ASKED US TO TURN IMMEDIATELY TO A 090 DEG HDG. WE COMPLIED, AND DEP ASKED US WHAT HEADING TWR HAD ASSIGNED US. WE REPLIED 020 DEGS. HE CHKED WITH TWR, CAME BACK AND TOLD US TWR HAD US FLY 070 DEG HDG. WE SAID NO, TO PULL THE TAPES IF HE HAD TO. HE (DEP) THEN TURNED US TO A 330 DEG HDG AND HANDED US OFF TO CTR. NO TCASII TA'S OR RA'S RESULTED. SUPPLEMENTAL INFO FROM ACN 536577: ATL TWR CLRED US FOR TKOF FROM RWY 8R AND TURN TO A 020 DEG HDG AT THE MM. I TOLD DEP CTL TO PULL THE TAPES IF THEY DIDN'T BELIEVE ME. DEP CTL THEN TOLD US 'IT WAS NO BIG DEAL.' (IT'S A BIG DEAL TO ME IF I'M GOING TO HIT ANOTHER ACFT.) I FEEL THAT POOR VISIBILITY WAS A FACTOR FOR TWR AND THEY JUST GOT US OUT OF SEQUENCE OR MIXED UP FROM WHERE THEY THOUGHT WE WERE, WHICH MIGHT BE THE REASON THEY ASSIGNED US THE WRONG DEP HDG OF 020 DEGS INSTEAD OF 070 DEGS WHICH THEY SAY THEY ASSIGNED US.
