Narrative:

After landing on runway 17C at dfw, we were told to cross runway 17R at taxiway el behind the F100 in front of us. We crossed the main portion of the runway, but could not continue to clear the runway as the F100 in front of us had stopped short of taxiway left. I do not know if the aircraft in front of us had been cleared up to taxiway K or not. I don't believe that he was given that instruction and apparently had no idea that we were directly behind him. There was a widebody transport aircraft in position for takeoff on runway 17R and I was not sure if my tail was completely clear of the runway. I moved up as close as I could and rapidly switched to 121.8 and attempted to barge in on the frequency to make the aircraft in front aware of our dire predicament. There was a long stream of ATC ground instructions being given to other aircraft and I was unable to get through. I could not tell if the widebody transport on the runway was rolling or not, and I was just about to go back to tower frequency and tell him to abort his roll if he had started, when the aircraft in front of us moved up and we were able to completely clear the runway. This situation must not be allowed to happen again and I have 2 suggestions to help prevent it in the future: 1) tower controllers must always instruct the first plane to pull all the way up to taxiway K, and 2) all pilots must be more precise and read back the instructions given by tower so that there is no chance of misunderstanding. I contacted the east tower supervisor after reaching the gate, and informed him of the situation in case he wanted to review the tapes.

Title: AN F100 CREW, AFTER LNDG AT DFW, WERE UNABLE TO CLR A PARALLEL RWY AS INSTRUCTED, DUE TO ANOTHER ACFT STOPPED IN FRONT OF THEM.

Narrative: AFTER LNDG ON RWY 17C AT DFW, WE WERE TOLD TO CROSS RWY 17R AT TXWY EL BEHIND THE F100 IN FRONT OF US. WE CROSSED THE MAIN PORTION OF THE RWY, BUT COULD NOT CONTINUE TO CLR THE RWY AS THE F100 IN FRONT OF US HAD STOPPED SHORT OF TXWY L. I DO NOT KNOW IF THE ACFT IN FRONT OF US HAD BEEN CLRED UP TO TXWY K OR NOT. I DON'T BELIEVE THAT HE WAS GIVEN THAT INSTRUCTION AND APPARENTLY HAD NO IDEA THAT WE WERE DIRECTLY BEHIND HIM. THERE WAS A WDB ACFT IN POS FOR TKOF ON RWY 17R AND I WAS NOT SURE IF MY TAIL WAS COMPLETELY CLR OF THE RWY. I MOVED UP AS CLOSE AS I COULD AND RAPIDLY SWITCHED TO 121.8 AND ATTEMPTED TO BARGE IN ON THE FREQ TO MAKE THE ACFT IN FRONT AWARE OF OUR DIRE PREDICAMENT. THERE WAS A LONG STREAM OF ATC GND INSTRUCTIONS BEING GIVEN TO OTHER ACFT AND I WAS UNABLE TO GET THROUGH. I COULD NOT TELL IF THE WDB ON THE RWY WAS ROLLING OR NOT, AND I WAS JUST ABOUT TO GO BACK TO TWR FREQ AND TELL HIM TO ABORT HIS ROLL IF HE HAD STARTED, WHEN THE ACFT IN FRONT OF US MOVED UP AND WE WERE ABLE TO COMPLETELY CLR THE RWY. THIS SIT MUST NOT BE ALLOWED TO HAPPEN AGAIN AND I HAVE 2 SUGGESTIONS TO HELP PREVENT IT IN THE FUTURE: 1) TWR CTLRS MUST ALWAYS INSTRUCT THE FIRST PLANE TO PULL ALL THE WAY UP TO TXWY K, AND 2) ALL PLTS MUST BE MORE PRECISE AND READ BACK THE INSTRUCTIONS GIVEN BY TWR SO THAT THERE IS NO CHANCE OF MISUNDERSTANDING. I CONTACTED THE E TWR SUPVR AFTER REACHING THE GATE, AND INFORMED HIM OF THE SIT IN CASE HE WANTED TO REVIEW THE TAPES.
