Narrative:

We were given position and hold by stl tower behind a X aircraft on runway 30L at taxiway south. We were over the hold short line when the X aircraft suddenly added a large amount of power and exited the runway on the other side. We stopped and at this time we could see a dc-9 on a go around at approximately 100 ft. We were over the hold line but clear of the runway. ATIS was M5 overcast 3 but the tower said that he had us on radar but could not see us. He asked if we were on the runway or was the X aircraft tower at stl is approximately 120 ft and could not see the end of runway 30L. The X aircraft turned around and departed then we did with no further incident. The tower operator said that he had no knowledge about the dc-9 and it would be investigated. Callback conversation with reporter revealed the following information: the reporter and the saab were to depart from runway 30L and the inbound dc-9 was to land on runway 30R. For some unknown reason, the dc-9 was lined up on the wrong runway, runway 30L. All 3 aircraft reacted correctly when they saw the problem. The reporter has not heard anything more from his air carrier or the FAA on this matter.

Narrative: WE WERE GIVEN POS AND HOLD BY STL TWR BEHIND A X ACFT ON RWY 30L AT TXWY S. WE WERE OVER THE HOLD SHORT LINE WHEN THE X ACFT SUDDENLY ADDED A LARGE AMOUNT OF PWR AND EXITED THE RWY ON THE OTHER SIDE. WE STOPPED AND AT THIS TIME WE COULD SEE A DC-9 ON A GAR AT APPROX 100 FT. WE WERE OVER THE HOLD LINE BUT CLR OF THE RWY. ATIS WAS M5 OVCST 3 BUT THE TWR SAID THAT HE HAD US ON RADAR BUT COULD NOT SEE US. HE ASKED IF WE WERE ON THE RWY OR WAS THE X ACFT TWR AT STL IS APPROX 120 FT AND COULD NOT SEE THE END OF RWY 30L. THE X ACFT TURNED AROUND AND DEPARTED THEN WE DID WITH NO FURTHER INCIDENT. THE TWR OPERATOR SAID THAT HE HAD NO KNOWLEDGE ABOUT THE DC-9 AND IT WOULD BE INVESTIGATED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR AND THE SAAB WERE TO DEPART FROM RWY 30L AND THE INBOUND DC-9 WAS TO LAND ON RWY 30R. FOR SOME UNKNOWN REASON, THE DC-9 WAS LINED UP ON THE WRONG RWY, RWY 30L. ALL 3 ACFT REACTED CORRECTLY WHEN THEY SAW THE PROB. THE RPTR HAS NOT HEARD ANYTHING MORE FROM HIS ACR OR THE FAA ON THIS MATTER.
