The Astrobee D IV (D) was a complex 2 1/2 stage rocket with two flight computers, two on board cameras, five composite and black powdered motors, three black powdered charges, and over twenty feet of wiring throughout the rocket.  Although the rocket reached only a minimal altitude of around 400 feet, all systems including multiple backup safety components worked to perfection and were ultimately responsible for landing the rocket without incident 1000 feet downrange.
