Narrative:

Dca tower cleared us 'into position and hold runway 15' following an small transport Y powering up for takeoff. After approximately 1-2 minutes 'in position', tower came back saying he 'had not' cleared us onto the runway. I told him that in fact he had done so. No reply. Seconds later, we were cleared for takeoff and nothing more was said. I believe, due to the very heavy traffic, tower was confused as to his instructions to us.
