Narrative:

We had received a clearance which included a requirement to advise gray clearance/departure when we were number one for departure at kileen, tx. As we approached the runway, we were busy conducting our first flight of the day checks. The captain briefed me for departure, then asked if I had any questions. He then asked me to clear final and called for the before takeoff checklist (he had started to back taxi into position for a runway 19 departure). I made the advisory call on 122.7 (CTAF) and continued the complete checklist. As I was finishing the checklist, the captain had already advanced the throttles to 40 percent torque, and transferred the controls to me, saying 'lets go.' while we started to roll down the runway, I remembered that we needed to be released prior to our departure and notified the captain. I made a quick call to clearance, but the controller was in the process of communicating with the aircraft holding behind us. I focused back on our aircraft, since we were passing through V1 and had to respond to the standard call outs. I then attempted another call to clearance. The controller had us clarify that we were number one. I responded that we were and had just taken off. The controller had us identify, and then told us to proceed onto the lamps one departure. We were so busy rushing through our checks, and so glad that we were departing before every one else that we forgot to ask for our release prior to taking off from kileen. I was so distracted with my cockpit duties that I forgot to properly stop the captain from taxiing onto the runway for departure prior to getting our release.

AS WE APCHED THE RWY, WE WERE BUSY CONDUCTING OUR FIRST FLT OF THE DAY CHKS. THE CAPT BRIEFED ME FOR DEP, THEN ASKED IF I HAD ANY QUESTIONS. HE THEN ASKED ME TO CLR FINAL AND CALLED FOR THE BEFORE TKOF CHKLIST (HE HAD STARTED TO BACK TAXI INTO POS FOR A RWY 19 DEP).

AS I WAS FINISHING THE CHKLIST, THE CAPT HAD ALREADY ADVANCED THE THROTTLES TO 40 PERCENT TORQUE, AND TRANSFERRED THE CTLS TO ME, SAYING 'LETS GO.' WHILE WE STARTED TO ROLL DOWN THE RWY, I REMEMBERED THAT WE NEEDED TO BE RELEASED PRIOR TO OUR DEP AND NOTIFIED THE CAPT.
