making three passes through the cloud.

For the secondary purpose of obtaining data on shock wave
intensity, four (4) of the drone aircraft were equipped with special
data recording devices as well as flight analyzer equipment.
These four
(4) drone aircraft were those stationed at 14,000, 20,000, 22,000, and
28,000 feet altitudes.
On the first test, these aircraft were at least
ten (10) miles out from zero point at the time of detonation.
Location
of the drone aircraft was determined as follows:
(1)
Radar tracking of drone aircraft by S-band shipboard
radar, with scope photographs taken in order to determine azimuth and range.
(2)
For date on vertical displacement of all drone aircraft,
movie filmwas taken of the radar altimeter scope reading aboard each drone
versus barometric reading and time.
(3)
Pictures were taken every three seconds from a vertically
mounted, X-17 camera in each drone aircraft as a possible aid in determing
azimuth and range position.

APS-10 scope camereswere installed in four (4) drones.
Aerial photographic coverage was accomplished by the photo-
graphic airoraft, Task Unit 7.4.3.
Specially assigned personnel of 7.4.2,
assisted by personnel of 7.465, also maintained and serviced all motion.

TECHNICAL PROCEDURES TO MEET TEST REQUIREMENTS
For the primary purpose of collecting air samples for the Atomic
Energy Commission, air filters containing special filter paper were installed on the top and bottom of each drone aircraft.
Servicing of these
filters was accomplished by Atomic Energy Commission personnel, but Task
