Project 23.2 ~ Cloud Photography ~ H. E. Grier
D. Berkowitz
Approximate measurements on 70mm cloud camera film indicates the
following cloud dimensions at stabilization, roughly six minutes after zero
times
Height above cloud horizon
60,000 feet
Top of clouds
10,000 feet
Cloud error
12,000 feet
Height of cloud
82,000 feet
Diameter
100,000 feet
The "cloud error" is due to measuring from the cloud horizon rather than
from where the stem pops out of the clouds.
Measurements were made on film #36442 exposed in cloud camera #6 in
aircraft #7135.
