Narrative:
Aircraft was cleared to cross bucks at 8000 ft from 14000 ft at 210 KTS. Due to the strong tailwinds and distance, we ended up crossing at 9000 ft even with #2 and #3 engines in reverse to aid in descent. Corrective action: I should have slowed more and we should have been cleared to 8000 ft sooner, due to the ground speed which was high due to the high winds. Also, think that some ATC people are not aware that DC8's do not have in-flight spoilers to aid in dscnts.

Title: DC8 ACFT WITH CLRNC TO CROSS INTXN AT 8000 FT, CROSSED AT 9000 FT. RPTR CAPT ATTRIBUTES TO TAILWIND AND LACK OF SPOILERS.
Narrative: ACFT WAS CLRED TO CROSS BUCKS AT 8000 FT FROM 14000 FT AT 210 KTS. DUE TO THE STRONG TAILWINDS AND DISTANCE, WE ENDED UP XING AT 9000 FT EVEN WITH #2 AND #3 ENGS IN REVERSE TO AID IN DSCNT. CORRECTIVE ACTION: I SHOULD HAVE SLOWED MORE AND WE SHOULD HAVE BEEN CLRED TO 8000 FT SOONER, DUE TO THE GND SPD WHICH WAS HIGH DUE TO THE HIGH WINDS. ALSO, THINK THAT SOME ATC PEOPLE ARE NOT AWARE THAT DC8'S DO NOT HAVE INFLT SPOILERS TO AID IN DSCNTS.
