Operations:
Sampling devices on F-84, WB-29, and B-36 aircraft were
used to obtain nuclear debris samples close in to the detonations.
Long-range calibration samples were also collected by WB-29 aircraft.
Aircraft generally did not enter the cloud until 2 hours after burst;
the clouds were followed for 5 to 7 hours while samples were being
obtained.
Collection of close-in particulate samples was under the
technical direction of LASL, gas sample collection was supervised by
Hq USAF, and gas separation and some analysis was performed by UCRL.
Shots:
All.
Radiation Exposure Potential:
Exposure potential existed for aircraft
crews, aS well as for those processing samples upon the aircraft's return and those decontaminating the aircraft.
Staffing:
Five people were definitely associated with this project,
three from the 1009th (two civilians, one military), one civilian from
LASL, and one civilian from UCRL.

A single project, Project 9.1, made up this program in order to determine the rise rate of the cloud and the height at which the cloud ceased
to rise.

(EG&G)
Technical aerial photography was conducted by LML, with
backup ground photography by EG&G in conjunction with its photography
work for LASL.
One RB-36 and three C-54 aircraft, each equipped with
two cameras, flew one mission per aircraft for all six shots.
