The structure would be placed with the front face normal to the
blast. It must be held fairly rigid, they do not want it to tunbdle or
move appreciably with the blast, since the object is to measure loading on
a rigid structure. It will be at ground level, will require an undere
ground base. (It was agreed that the prints for the Knothole Project 3.1
structure could be used for the aboveground portion.)
There will be about 40 channels of instrumentation on the
structure, to measure pressurestime. A recording station will be required
at some distance; Gilbert did not think it could be over 6000 ft from the
cube because of cable length limitations. Doll is working up his requirements for the recording shelter, it is not thought it will have to be
There is a possibility this may be tied in with Project 3.5;

wanted sone
pressure instrumentation among trees and there are
none on these islands
to the east of sero. The only trees are on the west
end of Eniirikku.
It was suggested that this cubicle might also
be put on
Enfirikku. Campbell has to build sane photo
structures over there anyway,
