The objective of this test was to determine the delivery capability
of the B-52 aircraft,
=
Instrumentation of the B-52 fo
(Apache) consisted of 710
oscillograph channels which recorded measurements from strein-gage bridges,
accelerometers, roll and pitch gyros, radiometers, control position transducers, thermocouples, pressure transducers, and calorimeters.
In addition,
14 cameras recoried photo-recorder instruments (14 channels), wing deflection, cloud coverage, and fireball rise and grovth.
