LCL CTLR CLRS RPTR'S ACFT FOR TKOF WITH A COMMUTER ACFT STILL ON THE RWY.

Narrative

TAXIED OUT FROM RAMP TO RWY 27R. THIS IS A VERY SHORT TAXI. TWR ASKED IF WE WERE READY FOR TKOF AND WE TOLD THEM WE WERE NOT. AFTER WE COMPLETED CHKLIST WE TOLD THE TWR WE WERE READY. AFTER LNDG COMMUTER PLANE WE WERE CLRED INTO POS AND HOLD. WE TAXIED ONTO RWY; THE COMMUTER WAS STILL ON RWY. TWR CLRED US FOR TKOF AND WE WERE STILL LOOKING AT THE TAIL OF THE LNDG COMMUTER PLANE ON THE RWY. THE TWR SAID AGAIN YOU ARE CLRED FOR TKOF AND MY COPLT SAID THAT THE PLANE IS STILL ON THE RWY. THE TWR COMES BACK THAT THE PLANE IS OFF THE RWY. THE COMMUTER PLANE IS NOW STARTED TO TURN OFF BECAUSE I CAN SEE THE SIDE OF THE PLANE. I START MY TKOF. THE COPLT AND TWR ARE STILL DISCUSSING THAT THE PLANE WAS CLR OR NOT. THERE ARE 2 DIFFERENT VOICES COMING FROM THE TWR AND BOTH ARE SAYING THAT THE PLANE IS CLR OF THE RWY. THE TWR THEN CANCELED OUR TKOF CLRNC AND TO EXIT FIRST TURNOFF TO R. THIS TURNOFF IS A HIGH SPD TURNOFF FOR RWY 9L; WHICH I MADE BUT TOOK SOME WORK BECAUSE OF THE SIZE OF DC8. THE LNDG PLANE HAD TO GAR. AFTER EXITING RWY I ASKED FOR THE TWR PHONE NUMBER SO I COULD TALK TO THE SUPVR BUT I WAS TOLD HE WAS THE SUPVR AND THEY DID NOT GIVE ME THE NUMBER. 1) WHY WOULD WE LIE ABOUT THE PLANE ON THE RWY? 2) WHY ARE WE CLRED TO TKOF BEFORE THE PLANE EVEN STARTS TO TURN OFF? 3) WHY IS TWR SO ARGUMENTATIVE? 4) WHY TAKE OFF A PLANE WITH TFC SO CLOSE TOGETHER?
