Narrative:

We were cleared for takeoff on runway 28 at cle. As the first officer read back the clearance I spooled the engines up and released the brakes. We were barely moving when the tower cleared large transport Y for takeoff on runway 5R. I looked to my left and saw large transport Y starting his takeoff roll. Since these are intersecting runways, I rejected my takeoff. At the time we were moving at about the speed of a fast taxi and I easily turned off at the first exit which is short of 5R. We told the tower what we were doing and he said we must have blocked each other out when he cancelled our takeoff clearance, and we were reading back the takeoff clearance. We never heard anything except the other aircraft being cleared for takeoff. I'm a little surprised that he cleared another aircraft to go before we acknowledged that our takeoff clearance was cancelled. Supplemental information from acn 140700: I called the tower to tell them of the abort and in a very unconcerned, do not bother me voice, the tower replied, 'that's good. You must have acknowledged the clearance at the same time I was cancelling your clearance.' at no time had I heard or acknowledged the cancellation of our takeoff clear, nor had the tower bothered nor attempted to repeat the clearance cancellation and get acknowledgement from us. If conditions other than VFR existed, we would not have seen the other aircraft.

Title: GND CONFLICT AND CONFLICTING TKOF CLRNCS FOR 2 ACR ACFT ON INTERSECTING RWYS AT CLE.

Narrative: WE WERE CLRED FOR TKOF ON RWY 28 AT CLE. AS THE F/O READ BACK THE CLRNC I SPOOLED THE ENGS UP AND RELEASED THE BRAKES. WE WERE BARELY MOVING WHEN THE TWR CLRED LGT Y FOR TKOF ON RWY 5R. I LOOKED TO MY LEFT AND SAW LGT Y STARTING HIS TKOF ROLL. SINCE THESE ARE INTERSECTING RWYS, I REJECTED MY TKOF. AT THE TIME WE WERE MOVING AT ABOUT THE SPD OF A FAST TAXI AND I EASILY TURNED OFF AT THE FIRST EXIT WHICH IS SHORT OF 5R. WE TOLD THE TWR WHAT WE WERE DOING AND HE SAID WE MUST HAVE BLOCKED EACH OTHER OUT WHEN HE CANCELLED OUR TKOF CLRNC, AND WE WERE READING BACK THE TKOF CLRNC. WE NEVER HEARD ANYTHING EXCEPT THE OTHER ACFT BEING CLRED FOR TKOF. I'M A LITTLE SURPRISED THAT HE CLRED ANOTHER ACFT TO GO BEFORE WE ACKNOWLEDGED THAT OUR TKOF CLRNC WAS CANCELLED. SUPPLEMENTAL INFO FROM ACN 140700: I CALLED THE TWR TO TELL THEM OF THE ABORT AND IN A VERY UNCONCERNED, DO NOT BOTHER ME VOICE, THE TWR REPLIED, 'THAT'S GOOD. YOU MUST HAVE ACKNOWLEDGED THE CLRNC AT THE SAME TIME I WAS CANCELLING YOUR CLRNC.' AT NO TIME HAD I HEARD OR ACKNOWLEDGED THE CANCELLATION OF OUR TKOF CLR, NOR HAD THE TWR BOTHERED NOR ATTEMPTED TO REPEAT THE CLRNC CANCELLATION AND GET ACKNOWLEDGEMENT FROM US. IF CONDITIONS OTHER THAN VFR EXISTED, WE WOULD NOT HAVE SEEN THE OTHER ACFT.
