Narrative:

We took off on runway 25R at las; and climbing through 200-300 ft AGL; tower said that there was an aircraft on a go around on one of the 19 runways; and requested that we 'stay low through the intersection.' looking over to the right; we could see a B737-200 flying level over runway 19; apparently co-altitude with us and on a collision course. Not knowing if the first officer understood what tower was requesting; I directed him to level off; which he did at about 400 ft AGL; reducing thrust to maintain about 170 KTS. Tower informed us that the other aircraft was going to climb; which it did after a short moment. The TCAS symbology showed the other aircraft 600 ft above us as it passed directly overhead. The situation raises a number of questions. For one thing; why wasn't the other aircraft climbing as part of its go around? The first officer and I talked about what we could have done had the other aircraft not climbed; and it didn't seem like we had any foolproof options. The first officer said he was planning on turning left if the other aircraft hadn't climbed. My belief was that a r-hand turn would have provided separation from the other aircraft; whereas a left turn would not have. There were too many ways for this to go wrong -- congested radios; confusion over tower's instructions; indecision and others. The fact that things worked out as tower directed was largely due to luck; and I wouldn't want to depend on that next time. Supplemental information from acn 688152: I was on the verge of executing a steep turn away from the aircraft when the other aircraft suddenly pitched up aggressively and started to climb.

Title: B737 FLT CREW HAS TO TAKE EVASIVE MANEUVERS DURING TKOF TO AVOID ANOTHER ACFT ON A MISSED APCH.

Narrative: WE TOOK OFF ON RWY 25R AT LAS; AND CLBING THROUGH 200-300 FT AGL; TWR SAID THAT THERE WAS AN ACFT ON A GAR ON ONE OF THE 19 RWYS; AND REQUESTED THAT WE 'STAY LOW THROUGH THE INTXN.' LOOKING OVER TO THE R; WE COULD SEE A B737-200 FLYING LEVEL OVER RWY 19; APPARENTLY CO-ALT WITH US AND ON A COLLISION COURSE. NOT KNOWING IF THE FO UNDERSTOOD WHAT TWR WAS REQUESTING; I DIRECTED HIM TO LEVEL OFF; WHICH HE DID AT ABOUT 400 FT AGL; REDUCING THRUST TO MAINTAIN ABOUT 170 KTS. TWR INFORMED US THAT THE OTHER ACFT WAS GOING TO CLB; WHICH IT DID AFTER A SHORT MOMENT. THE TCAS SYMBOLOGY SHOWED THE OTHER ACFT 600 FT ABOVE US AS IT PASSED DIRECTLY OVERHEAD. THE SITUATION RAISES A NUMBER OF QUESTIONS. FOR ONE THING; WHY WASN'T THE OTHER ACFT CLBING AS PART OF ITS GAR? THE FO AND I TALKED ABOUT WHAT WE COULD HAVE DONE HAD THE OTHER ACFT NOT CLBED; AND IT DIDN'T SEEM LIKE WE HAD ANY FOOLPROOF OPTIONS. THE FO SAID HE WAS PLANNING ON TURNING L IF THE OTHER ACFT HADN'T CLBED. MY BELIEF WAS THAT A R-HAND TURN WOULD HAVE PROVIDED SEPARATION FROM THE OTHER ACFT; WHEREAS A L TURN WOULD NOT HAVE. THERE WERE TOO MANY WAYS FOR THIS TO GO WRONG -- CONGESTED RADIOS; CONFUSION OVER TWR'S INSTRUCTIONS; INDECISION AND OTHERS. THE FACT THAT THINGS WORKED OUT AS TWR DIRECTED WAS LARGELY DUE TO LUCK; AND I WOULDN'T WANT TO DEPEND ON THAT NEXT TIME. SUPPLEMENTAL INFO FROM ACN 688152: I WAS ON THE VERGE OF EXECUTING A STEEP TURN AWAY FROM THE ACFT WHEN THE OTHER ACFT SUDDENLY PITCHED UP AGGRESSIVELY AND STARTED TO CLB.
