Interns working at United Launch Alliance have built and launched two suborbital rockets from a site in Colorado, according to a space.com story. Billed as the "largest sport rocket launched in the world," the Future Heavy was 50 feet (15.24 m) in length and was designed to reach an apogee of 10,000 feet (3 km); the Genesis rocket measured 10 feet (3 m). Several payloads were lofted, including "a kindergarten experiment in solar physics."

Then Top Gear and their Reliant Robin shuttle probably win.
1/3rd of the altitude, but definitely larger and more fun.

It has to land successfully. The Reliant Robin landed with a big badda boom. Similarly... At one of the LDRS events a high powered rocket made a 180 and hit the ground at just over mach 1. The sonic boom just as it hit the ground liquefied the soil for a few minutes, then solidified. It took a backhoe to dig it out.
