I built an SR-71 model rocket. It was Estes, not Revell, and looked like this [0]. It was very difficult to build compared to other models, because it had three cylinders with webbing for the fuselage and engines. I remember being disappointed that the two outer cylinders were not designed to take individual model rocket engines. There was only one in the center. I guess it would have been too hard to ignite them synchronously. When I launched it (vertically of course), the plane seemed to hover forever on the launchpad before finally overcoming gravity and taking off. It did not achieve Mach 3.5 or anything significant for a rocket of its size. When it reached the ejection stage, it popped off the front cabin "nosecone", looking very ungainly as it fluttered to the ground on a parachute. I still have that model somewhere downstairs.
