Narrative:

We were told to taxi to runway 15L via wa. Nearing the runway, ground control told us to monitor tower 127.3. Tower told a B737 to takeoff runway 15L and immediately told us to taxi into position and hold 15L. We read back the clearance. I saw a B737, but it was to our right, about 100 yds further away from runway 15L than us... Is this the B737? Can't be... I thought! So we are in position and hold 15L and the B737 tells tower that a falcon 'jumped ahead' of him. We then asked the tower if we were cleared position and hold 15L! He said 'yes, he thought that the B737 was taxiing faster than what they were and that he was already on takeoff!' we were clear for take off and then I heard the tower tell the B737, 'let's try this again... Cleared for takeoff.' I was amazed this occurred... I heard the xmissions, but was confused thinking how could two different clrncs be given at the same time. I should have just stopped, but I was sort of taken back in surprise by it all! As for the tower controller, he must not have even looked out the window... Very scary! I now see how runway incursions happen.

Title: A FALCON 50 FLC IS ACCUSED BY A FLC OF A TAXIING B737 OF 'JUMPING IN AHEAD OF THEM' AFTER BOTH ACFT HAD RECEIVED INDIVIDUAL TKOF CLRNCS FROM RWY 15L AT IAH, TX.

Narrative: WE WERE TOLD TO TAXI TO RWY 15L VIA WA. NEARING THE RWY, GND CTL TOLD US TO MONITOR TWR 127.3. TWR TOLD A B737 TO TKOF RWY 15L AND IMMEDIATELY TOLD US TO TAXI INTO POSITION AND HOLD 15L. WE READ BACK THE CLRNC. I SAW A B737, BUT IT WAS TO OUR R, ABOUT 100 YDS FURTHER AWAY FROM RWY 15L THAN US... IS THIS THE B737? CAN'T BE... I THOUGHT! SO WE ARE IN POSITION AND HOLD 15L AND THE B737 TELLS TWR THAT A FALCON 'JUMPED AHEAD' OF HIM. WE THEN ASKED THE TWR IF WE WERE CLRED POSITION AND HOLD 15L! HE SAID 'YES, HE THOUGHT THAT THE B737 WAS TAXIING FASTER THAN WHAT THEY WERE AND THAT HE WAS ALREADY ON TKOF!' WE WERE CLEAR FOR TAKE OFF AND THEN I HEARD THE TWR TELL THE B737, 'LET'S TRY THIS AGAIN... CLEARED FOR TKOF.' I WAS AMAZED THIS OCCURRED... I HEARD THE XMISSIONS, BUT WAS CONFUSED THINKING HOW COULD TWO DIFFERENT CLRNCS BE GIVEN AT THE SAME TIME. I SHOULD HAVE JUST STOPPED, BUT I WAS SORT OF TAKEN BACK IN SURPRISE BY IT ALL! AS FOR THE TWR CTLR, HE MUST NOT HAVE EVEN LOOKED OUT THE WINDOW... VERY SCARY! I NOW SEE HOW RWY INCURSIONS HAPPEN.
