Narrative:

At stl one controller was controling ground, tower and departure. We were given taxi instruction and while we were close to the runway, were given takeoff clearance. We announced 'rolling' for takeoff. The controller said nothing. After takeoff the controller gave us a number to call. We called and he said he did not give us takeoff clearance, which he did. I believe that one controller should not be controling ground, tower and departure, and they should be rotated regularly to keep them fresh and alert.

Original NASA ASRS Text

Title: SH360 DEPARTS STL WITHOUT TKOF CLRNC ACCORDING TO ATC.

Narrative: AT STL ONE CTLR WAS CTLING GND, TWR AND DEP. WE WERE GIVEN TAXI INSTRUCTION AND WHILE WE WERE CLOSE TO THE RWY, WERE GIVEN TKOF CLRNC. WE ANNOUNCED 'ROLLING' FOR TKOF. THE CTLR SAID NOTHING. AFTER TKOF THE CTLR GAVE US A NUMBER TO CALL. WE CALLED AND HE SAID HE DID NOT GIVE US TKOF CLRNC, WHICH HE DID. I BELIEVE THAT ONE CTLR SHOULD NOT BE CTLING GND, TWR AND DEP, AND THEY SHOULD BE ROTATED REGULARLY TO KEEP THEM FRESH AND ALERT.
