Narrative:

Cleared for taxi across runway 18R at dfw at same time another was taking of. We were rolling on the hi speed when ground gave us the clearance to cross the left runway. I saw the aircraft on the runway holding in position. As I entered the runway it appeared the other aircraft was moving, I thought he was taxiing. I then realized he was on takeoff roll so I added power and got about half of my aircraft off the runway when he overflew me by approximately 100 ft. I believe the next time I'm cleared to roll across an active runway with an aircraft in position, I will stop to make sure he's not moving. I should have had a greater attitude of vulnerability and 'expected' that the other aircraft could be rolling for takeoff!

Title: B737 CLRED TO CROSS RWY AS ANOTHER ACFT IS ON TKOF ROLL AT DFW.

Narrative: CLRED FOR TAXI ACROSS RWY 18R AT DFW AT SAME TIME ANOTHER WAS TAKING OF. WE WERE ROLLING ON THE HI SPEED WHEN GND GAVE US THE CLRNC TO CROSS THE LEFT RWY. I SAW THE ACFT ON THE RWY HOLDING IN POSITION. AS I ENTERED THE RWY IT APPEARED THE OTHER ACFT WAS MOVING, I THOUGHT HE WAS TAXIING. I THEN REALIZED HE WAS ON TKOF ROLL SO I ADDED PWR AND GOT ABOUT HALF OF MY ACFT OFF THE RWY WHEN HE OVERFLEW ME BY APPROX 100 FT. I BELIEVE THE NEXT TIME I'M CLRED TO ROLL ACROSS AN ACTIVE RWY WITH AN ACFT IN POSITION, I WILL STOP TO MAKE SURE HE'S NOT MOVING. I SHOULD HAVE HAD A GREATER ATTITUDE OF VULNERABILITY AND 'EXPECTED' THAT THE OTHER ACFT COULD BE ROLLING FOR TKOF!
