Narrative:
On departure from gso we had been given a turn to 310 degrees or so and were cleared to 9000 ft. Shortly after leveloff we noticed another aircraft also at 9000 ft and approximately 10 mi in our 12 O'clock position. I tried to mention this to the controller, but she was busy and discussed with the first officer about the possibility of having to do a TCASII RA climb or descent. Before I could get a word in to the departure controller, we received the TCASII RA and began the commanded descent. We ended up descending to approximately 8200 ft before the conflict was resolved. I did report the RA descent to the departure controller and also reported climbing back up to our assigned altitude of 9000 ft. The controller then handed us off to ZTL and never mentioned the near miss. The first officer did say that he saw the conflicting aircraft fly directly above us and most probably would have hit us if TCASII had not been working. We would like to thank the TCASII inventor because he saved us tonight.

Title: FK10 TAKES EVASIVE ACTION IN RESPONSE TO TCASII RA IN DFW AIRSPACE.
Narrative: ON DEP FROM GSO WE HAD BEEN GIVEN A TURN TO 310 DEGS OR SO AND WERE CLRED TO 9000 FT. SHORTLY AFTER LEVELOFF WE NOTICED ANOTHER ACFT ALSO AT 9000 FT AND APPROX 10 MI IN OUR 12 O'CLOCK POS. I TRIED TO MENTION THIS TO THE CTLR, BUT SHE WAS BUSY AND DISCUSSED WITH THE FO ABOUT THE POSSIBILITY OF HAVING TO DO A TCASII RA CLB OR DSCNT. BEFORE I COULD GET A WORD IN TO THE DEP CTLR, WE RECEIVED THE TCASII RA AND BEGAN THE COMMANDED DSCNT. WE ENDED UP DSNDING TO APPROX 8200 FT BEFORE THE CONFLICT WAS RESOLVED. I DID RPT THE RA DSCNT TO THE DEP CTLR AND ALSO RPTED CLBING BACK UP TO OUR ASSIGNED ALT OF 9000 FT. THE CTLR THEN HANDED US OFF TO ZTL AND NEVER MENTIONED THE NEAR MISS. THE FO DID SAY THAT HE SAW THE CONFLICTING ACFT FLY DIRECTLY ABOVE US AND MOST PROBABLY WOULD HAVE HIT US IF TCASII HAD NOT BEEN WORKING. WE WOULD LIKE TO THANK THE TCASII INVENTOR BECAUSE HE SAVED US TONIGHT.
