Narrative:

We were holding in position on runway 30L when the tower controller issued us takeoff clearance. As we began to run up our engines both the first officer and myself simultaneously called out a B757 (Y) that had not cleared the runway. This B757 made the 90 degree turn off runway 30L onto taxiway M or taxiway A8 and stopped with his tail sticking well into runway 30L. We notified the tower controller who correctly canceled our takeoff clearance and asked us to exit the runway to the left for landing traffic which we did. One mistake for the tower controller which we caught prior to takeoff roll. We were cleared into position again and then cleared for takeoff. The identical situation was present again with a B747 (Z) that had made the 90 degree turn and stopped prior to taxiway a with its tail over the runway. Again we notified the tower that the B747 had not cleared the runway but by the time we got the call out on the radio the B747 began to move and subsequently cleared. The controller's response was the aircraft was clear so we released brakes and began our takeoff roll. However, the tower made the same error twice by issuing takeoff clearance with an aircraft stopped on taxiway M or taxiway A8 with its tail protruding into the runway. On each occasion there was landing traffic behind us and the controller was obviously trying to rush but safety was compromised by this controller each time. Once is a mistake, but twice is unacceptable.

Title: F100 FLC ALERT MSP TWR THAT RWY NOT CLR DUE TO EXITING ACFT AFTER MSP HAS CLRED F100 FOR TKOF.

Narrative: WE WERE HOLDING IN POS ON RWY 30L WHEN THE TWR CTLR ISSUED US TKOF CLRNC. AS WE BEGAN TO RUN UP OUR ENGS BOTH THE FO AND MYSELF SIMULTANEOUSLY CALLED OUT A B757 (Y) THAT HAD NOT CLRED THE RWY. THIS B757 MADE THE 90 DEG TURN OFF RWY 30L ONTO TXWY M OR TXWY A8 AND STOPPED WITH HIS TAIL STICKING WELL INTO RWY 30L. WE NOTIFIED THE TWR CTLR WHO CORRECTLY CANCELED OUR TKOF CLRNC AND ASKED US TO EXIT THE RWY TO THE L FOR LNDG TFC WHICH WE DID. ONE MISTAKE FOR THE TWR CTLR WHICH WE CAUGHT PRIOR TO TKOF ROLL. WE WERE CLRED INTO POS AGAIN AND THEN CLRED FOR TKOF. THE IDENTICAL SIT WAS PRESENT AGAIN WITH A B747 (Z) THAT HAD MADE THE 90 DEG TURN AND STOPPED PRIOR TO TXWY A WITH ITS TAIL OVER THE RWY. AGAIN WE NOTIFIED THE TWR THAT THE B747 HAD NOT CLRED THE RWY BUT BY THE TIME WE GOT THE CALL OUT ON THE RADIO THE B747 BEGAN TO MOVE AND SUBSEQUENTLY CLRED. THE CTLR'S RESPONSE WAS THE ACFT WAS CLR SO WE RELEASED BRAKES AND BEGAN OUR TKOF ROLL. HOWEVER, THE TWR MADE THE SAME ERROR TWICE BY ISSUING TKOF CLRNC WITH AN ACFT STOPPED ON TXWY M OR TXWY A8 WITH ITS TAIL PROTRUDING INTO THE RWY. ON EACH OCCASION THERE WAS LNDG TFC BEHIND US AND THE CTLR WAS OBVIOUSLY TRYING TO RUSH BUT SAFETY WAS COMPROMISED BY THIS CTLR EACH TIME. ONCE IS A MISTAKE, BUT TWICE IS UNACCEPTABLE.
