At 1:58 the pilot says "it's all yours". Now the plane is controled from the bombsight until the bombs are dropped. The Norden indicates when it's time to drop with a light, but the actual command is done with a button.

For what its worth, here is a few pages from the Norden technical manual. Note that the Norden automatically calculates TAS for you as well as flying the plane.
