PROGRAM_7,0 - LONG RANGE DETECTION
the world wide
Operation GREENHOUSE provided an opportunityfor testing
and alse permitted
detection net operated by Headquarters, United States Air Foree,
ting atomic
the gathering of much additional data which will be employed in evalua
explosions produced by foreign powers.
By collection of bomb debris in air and
s, measurcground filters, measurement of atmospheric shock wayos by acoustic device
ment of shock waves in the earth's crust by seismic instruments, and detection of
borib debris by atmospheric conductivity apparatus installed in aircraft, any suspected atomic explosion is capable of verification and, within Limits, description as to
location and yield.
Because many of the Air Force detection installations are lo-
cated in remote parts of the world, complete informition from the world wide net
concerning Operation GREENHOUSE has not yet beon correlated,
be drawn, however, on the information available.
Sone conclusions can
Collection of samples of bomb de-
bris was highly sucecssful and preliminary results are gratifying.
Acoustic signals
from all shots were identified at a distance of 2,500 naubical miles east and west
of ENIWSTOK.
Seismic installations detectcd all explosions at great distances, the
greatest being 5,200 nautical miles on two shats.,
Hach shot was also detected by
Sound, Finding and Ranging (SOFAR) equipment at Point Sur, California.
By Joint
Chiefs of Staff decision, the Commander, Joint Task Force THREE was only rcsponsible
for activities within the MARSHALL ISLANDS area.
Headquarters, USAF (AFOAT-1) shoul:
be consulted for further discussion of this program,

PROGRAM 8.0 — BLAST EFFECT ON ATRORAFT
This program was primarily concerned with pressure, gust end touperature
effects of an atomic explosion on aircraft in flight and on aircraft components on
the ground.
In addition, several specialiacd projects related to air operations and
blast were carricd on under this program,
a,
BLAST EFFECT ON ATRCRAFT
Structural damage, verying from negligible to fairly severe, occurred
on T~33 and B-l7 drone airplanes,
On "HASY" shot, one (1) 17-33 drone went out
of control shortly after arrival of the shock wave and crashed in the ocean.
No data wore obtained in this case since the telometoring system was inoperative
throughout all tests,
Some heat effects were noted on the drone aircraft, such
as scorched paint and a burned tire.
The crews of manned sircraft noted some,
