1.
Four B-36 aircraft.
(a)
Two B36 Featherweights for obtaining high altitude particulate and gas samples.
(>)
One B~36D for measuring blast, gust, and thermal
effects on aircraft in flight.
(c)
One RB-36 for the primary purpose of aircraft
control and secondary purpose of photography.
2.
Fifteen F-84G aircraft for particulate and gas sampling.
3.
Three C-54 aircraft for photography.
4.
Seven H-19 helicopters for certain ground sampling recovery and general logistic support.
In October, some consideration was still being give to the
possibility of utilizing the B-57 as a sampler aircraft during CASTLE.
Following more study of that aircraft's capabilities, CTG 7.4
outlined several reasons why it would not be practical for use.
The aircraft had developed an eight~cycle buffet at .72 Mach; it
still wallowed considerably at altitude; its ceiling was 48,600
feet which was well below the required altitude for sampling; cer-
tain engine difficulties had been experienced; it had limited range,
making flight from the West Coast to Hawaii impossible; and, finally, mission-required modifications would be difficult to effect.
In view of the above all thought of using the B-57 in CASTLE was
abandoned unless further tests proved more successful.
A companion problem to that above was the one of flight safety.
