Narrative:

Flying flight out of dayton holding short 24R. An air carrier was on final. We were waiting for weight and balance. Receiving our weight/balance we notified tower we were ready. Dayton tower cleared us into position and hold. We responded and took position. Tower then cleared us for an immediate takeoff. We responded and started takeoff. We were given 5000 ft and left to 220 degrees. Upon lift off I noticed a northwest commuter had just lifted off 24L. I questioned tower about our clearance. A long silence. Tower told us to hold runway heading, maintain 5000 ft. Traffic was in sight. There was never a traffic conflict. We were sent over to departure. At that time, I asked departure to call tower and see if they had a problem with our flight on takeoff. Departure responded no. We proceeded on to clt. Supplemental information from acn 200714: I switched off the lamprey receiver as the captain was responding to a takeoff clearance of cleared for immediate takeoff turn left heading 220 degrees. We took off and started a left turn. The tower seemed surprised that we were airborne and gave us a clearance to maintain runway heading, that there was traffic that departed on a parallel runway.
