IV. EVIDENCE FROM LOW YIELD DETONATION”
FollowIng:data.including.sketch.and illustration.weze obtained.by analysis.of
photogrophs.of smoke puffs In connection-with Tumbler 3. ...
Movement.of the smoke puffs clearly .troced.the:streamline.motion tn the surrounding —
ait mass-directly connected.with the.formation.of the Torus Ring. ‘Initial horizontal
velocity.ofburst.no. 1.was 200 feet.per second with.averoge.velocity.of 100 feet per
second, The initial velocity.of.burst.na2..which was at a gteater horizontal distance
from the detonation point, was 100 feet per second, The.averoge.velocity.was 65
feet per second, The.average velocity.of.the cloud top.was 970.feet per second.
