The supersonic transport (SST) was the future until dangerously loud sonic booms limited where these marvels could fly. The super-quiet Low-Boom SST could begin a new era of supersonic passenger flights. This highly detailed model rocket kit features laser-cut balsa parts, including realistic under-wing “engines pods” and a parachute recovery. Estes is looking ahead with its own Low-Boom SST – a sleek, 30-inch long, delta-winged model rocket of the next generation of quiet, super-fast passenger jets. This Expert level kit is loaded with features, including intricate, balsa-constructed, underwing engine pods and a large sheet of detailed water-slide decals to complete the scale-like look. Launch and watch as the Low-Boom SST climbs to 400 feet on a C6-3, engine and gently returns under a large 15 inch parachute. The SST revolution might be on its way after all!
