Here is a lengthy measage from Bradbury to Betts sent on9 September OL, which is also
ocumented under 8 September in the notes marked P.
I wish to note aalient points that
redbury makes at this point in time as to his feeling. for undersround testinz versus
arious atmospheric test concepts, which I did not get into detail on jin the astes

Bradbury says that LASL is generally of the opinion that it will prove somewhere
N S
etween impractical and impossible to test much beyond 1LCOKT underground, due to such
nings as adequate containment, ground water problems, and seismic effects.
LASL also
sn't convinced at this point in time that good yield measurments can be made on
adergroune shots which have an appreciabe TN contribution.
In spite of this, "if the
feld measurement problem can be surmounted, it is probable that underground testing up
2 100 KT or so can do
everything except air effects ezperinents that can be done in air."
1 addition to the yield flexibility offered by atmospheric testing, as vell as the
apability to make better measurements, the time factor seems to favor atmospneric testing
rere things could certainly be done more rapidly.
He estimates toe time it would take to
tpport air drops over tne open ocean with minimal diagnostics and feels that it would take
*ss than four to six months to prepare the necessary Naval and Air support.
Bradbury
‘els that Eniwetok could be cranked up for support such as in previous operations in
out four to six months if the trust territory question would be resolved in its favor.
*Eniwetok is not available, there is always Johnston Island for air drops or for deep
.chored barge shots and he would guess that six montns would be required to attain
‘adiness there.
He further discusses the fall-out problems, the possible
desirability of
number of system tests, and the possibility and mechanics of hiwth altitude tests.
