Didn’t the B-36 have pusher props on the trailing edge of the wing? I remember seeing cargo planes with rocket motors on the lower rear fuselage to help them take off under load especially with short runways. They called them JATO, jet assisted take off. But they looked and performed like rockets which give more thrust than jets.
Yes, they had pusher props. You can see in the Jimmy Stewart video they light off the four jets as well as the props for takeoff,
