rockoon
A rockoon (a portmanteau of rocket and balloon) was a solid fuel sounding rocket that, rather than being immediately lit while on the ground, was first carried into the upper atmosphere by a gas-filled balloon, and then separated from the balloon and automatically ignited. This would allow the rocket to achieve a higher altitude, since the rocket did not have to move under power through the lower, thicker, air layers.
