Here's a video of an remote control B-29 model carrying a remoted control X-1 rocket plane model. The B-29 takes off and drops the rocket plane. The rocket plane ignites and shoots upwards before coming back and landing. The B-29 model does a few fly bys of the camera including one where it flies by upside down and does a backwards loop. Both planes land safely verses other videos where they fly a big model and then crash it by mistake.
