Doorknob (2) (Scale) (English Only) Skill PRO
During the mid-1950’s, the public concerns over
nuclear fallout due to US and Russian testing was reaching a fevered
pitch. To that end, President Eisenhower announced to the US on August
22, 1958, 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 Hardtack Series of tests. Scientists where
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-August 1958. Scientists, at the time, were chiefly concerned
about damage to the ozone layer and possible effects of long-range
radioactive fallout and 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 and could launch an
instrument laden sounding rocket to approximately 50 miles in altitude
and capture radioactive data for analysis. Early results of this upper
atmosphere data suggested little to no damage to the ozone layer was
measured during the nuclear testing and water detonations probably
produced enough ozone to replace what little might have been lost due
to above ground testing.
The Estes 1:5.3 scale model Doorknob is big and impressive.
Simple to build and fun to fly, this kit will be big hit in both the
sport and scale rocket categories. This kit has two sets of decals
available for those who want to turn this scale model into a sports
model.
WHAT YOU NEED TO BUILD: Scissors, pencil, ruler, fine
sandpaper, epoxy, carpenter’s glue, sanding block, hobby
knife, masking tape, primer (white), paint (black, day glow orange,
white) and clear coat (optional). Tools, construction and finishing
supplies not included.
WHAT YOU NEED TO LAUNCH (sold separately): Porta-Pad
E Launch Pad and Pro
Series II Launch Controller, Estes
model rocket engines, starters
and recovery
wadding. Six C 1.5V high quality AA alkaline batteries are
also required for launch controller (not included).
