Description: Almost 27 inches tall and powered by E and F engines, this 1:12 Scale Model is an impressive Sport and Scale model of the sounding rocket manufactured from Lacrosse rocket motors for the project Hardtack Nuclear Test Series. During the mid-1950s, the public concerns over nuclear fallout due to US and Russian testing was reaching a fevered pitch. To that end, President Eisenhower announced on August 22, 1958, that the US would ban further nuclear testing on or before October 31 of the same year. US scientists, wanting to gather as much data as possible, responded with the "Hardtack" series of tests. Scientists were interested in many scientific areas, but primary interest lay in the effects of radioactivity from underwater and above ground detonation.The Hardtack Nuclear Testing Program consisted of 35 detonations in the Pacific Proving Grounds during the period of April through August of 1958. Scientists at the time were chiefly concerned about damage to the ozone layer and possible effects of long-range radioactive fallout. They determined that scientific measurements of the earth's upper atmosphere (aeronomy) would help clarify what, if any, damage had occurred.Single and two-stage Doorknob rockets were developed using Lacrosse and Thiokol solid propellent motors. The instrument-laden sounding rocket could be launched to approximately 50 miles in altitude to capture radioactive data for analysis. Early results of the upper atmosphere data measured little to no damage of the ozone layer during the nuclear testing. It was determined that water detonations probably produced enough ozone to replace what little might have been lost due to above-ground testing. The single-stage Estes 1:12 scale and sport model of the Doorknob is big and impressive. Simple to build and fun to fly, this kit includes a second set of decals for those who want to turn this scale model into a spectacular sports model.

Tools, glue, and paint (not included) are usually required to complete the kit. A motor, igniter, launch controller, and launch pad (not included) are required to fly the rocket. Adult supervision is required during the construction and flying of model rockets. Model rocket kits are often described in terms of their "Skill Level" - a number (usually 1 through 5) which represents the difficulty involved to construct, finish, a fly the kit. A Skill Level 1 kit requires little or no experience building model rockets while a Skill Level 5 kit requires much experience and special skills. For the kits we sell, we use a normalized Skill Level using a scale of 1 to 5: Skill Level 1 (Beginner) kits are easy to build. They usually include pre-cut fins and simple-to-follow instructions and require no special skills to build or fly. Skill Level 2 (Experienced) kits are usually a little harder to build than Skill Level 1 kits. Sometimes they require that fins be cut from supplied stock. A Skill Level 2 kit may present new challenges to a beginner such as requiring shaping of fins or wings or flying on a larger motor. Skill Level 3 (Advanced) kits may include instructions which assume that the builder has experience building rockets and does not need as much explicit instruction. They often include features, such as paper shrouds, which require more skill to construct. Skill Level 4 and 5 (Expert) kits are designed for experienced modelers and present the greatest challenges. Skill Level 4/5 kits are often scale models which require the builder to craft details and carefully mask areas to be painted. You may also see kits with Skill Level 0 (zero). These are Ready-To-Fly (RTF), Easy-To-Assemble (E2X), and Almost-Ready-To-Fly (ARF) kits which require little or no assembly or finishing. Usually, you can take the kit out of the box and it's ready to prep for flight. Even if labelled "Ready-To-Fly," some RTF kits do require a minor amount of assembly, such as attaching a streamer or shock cord.
