Narrative:

We had landed and were holding short of runway 35L at taxiway ek. The tower controller started clearing a group of about 5 planes to cross runway 35L and contact ground. She had cleared air carrier X to keep rolling and cross runway 35L down by terminal entry -- I couldn't see which taxiway. I looked to the left to check the runway before I started across and observed a plane on takeoff roll with black smoke coming out the back. I did not attempt to cross then but held position. I did, however, see air carrier X approaching the runway at a pretty good clip. It looked like he hadn't seen the F100 on takeoff roll and we attempted to warn on frequency but it was very busy and I don't think we got out. He did see the F100 at the last second and jammed his brakes on coming to a stop less than 1 ft from being in the runway. About 3 or 4 planes upfield from us did cross during this, although the F100 was airborne by the time it got to them. I think this brings up the point that just because the tower or whoever clears you to do it, you still need to check the runways and txwys to make sure what they have cleared you to do you can do.

Title: LOSS OF SEPARATION BTWN DEPARTING F100 AND AN ACR MD80 WITH RWY XING CLRNC FOR THE SAME RWY. ACR WAS PAST HOLD LINE BUT SHORT OF THE RWY WHEN IT STOPPED.

Narrative: WE HAD LANDED AND WERE HOLDING SHORT OF RWY 35L AT TXWY EK. THE TWR CTLR STARTED CLRING A GROUP OF ABOUT 5 PLANES TO CROSS RWY 35L AND CONTACT GND. SHE HAD CLRED ACR X TO KEEP ROLLING AND CROSS RWY 35L DOWN BY TERMINAL ENTRY -- I COULDN'T SEE WHICH TXWY. I LOOKED TO THE L TO CHK THE RWY BEFORE I STARTED ACROSS AND OBSERVED A PLANE ON TKOF ROLL WITH BLACK SMOKE COMING OUT THE BACK. I DID NOT ATTEMPT TO CROSS THEN BUT HELD POS. I DID, HOWEVER, SEE ACR X APCHING THE RWY AT A PRETTY GOOD CLIP. IT LOOKED LIKE HE HADN'T SEEN THE F100 ON TKOF ROLL AND WE ATTEMPTED TO WARN ON FREQ BUT IT WAS VERY BUSY AND I DON'T THINK WE GOT OUT. HE DID SEE THE F100 AT THE LAST SECOND AND JAMMED HIS BRAKES ON COMING TO A STOP LESS THAN 1 FT FROM BEING IN THE RWY. ABOUT 3 OR 4 PLANES UPFIELD FROM US DID CROSS DURING THIS, ALTHOUGH THE F100 WAS AIRBORNE BY THE TIME IT GOT TO THEM. I THINK THIS BRINGS UP THE POINT THAT JUST BECAUSE THE TWR OR WHOEVER CLRS YOU TO DO IT, YOU STILL NEED TO CHK THE RWYS AND TXWYS TO MAKE SURE WHAT THEY HAVE CLRED YOU TO DO YOU CAN DO.
