Narrative:
Took off runway 29 mso, following departure procedure for runway 29, tracking outbound 293 degree radial to 9600 ft. At about 8000 ft, mso tower advised traffic at 1 O'clock position, 5 mi. As PNF, I began looking for traffic. While looking for traffic, a TA was issued. Rate of climb was decreased, but by then an RA followed. Complied with RA until 'clear of conflict' issued. In retrospect, the entire problem here was traffic in the departure path of the active runway. We were climbing 3500-4000 FPM. The other airplane was around 9500 ft. There was not enough time or warning given. I never saw the other airplane, even though the WX was good.

Title: DC9 FLT CREW, ON DEP FROM MSO, RECEIVE A TA ON A VFR ENRTE ACFT AT 9500 FT, WHICH TURNS FROM A TA ALERT TO AN RA. PLT COMPLAINS ABOUT REACTION TIME FROM CTLR ISSUED ADVISORY TO RECEIVING A TCASII TA RA VERSUS ACFT CLB RATE.
Narrative: TOOK OFF RWY 29 MSO, FOLLOWING DEP PROC FOR RWY 29, TRACKING OUTBOUND 293 DEG RADIAL TO 9600 FT. AT ABOUT 8000 FT, MSO TWR ADVISED TFC AT 1 O'CLOCK POS, 5 MI. AS PNF, I BEGAN LOOKING FOR TFC. WHILE LOOKING FOR TFC, A TA WAS ISSUED. RATE OF CLB WAS DECREASED, BUT BY THEN AN RA FOLLOWED. COMPLIED WITH RA UNTIL 'CLR OF CONFLICT' ISSUED. IN RETROSPECT, THE ENTIRE PROB HERE WAS TFC IN THE DEP PATH OF THE ACTIVE RWY. WE WERE CLBING 3500-4000 FPM. THE OTHER AIRPLANE WAS AROUND 9500 FT. THERE WAS NOT ENOUGH TIME OR WARNING GIVEN. I NEVER SAW THE OTHER AIRPLANE, EVEN THOUGH THE WX WAS GOOD.
