Ie eeneT” the proper altitude, # Consequently, all parties preferred to use three B=36's, if at all possible. ‘Tt was agreed that a second controller was needed in the event one of the featherweight sampler=controllers should abort. About the same time, SAC reported its inability to send an RB-50 because RB~-50 crew members were attending RB-47 school. SAC then sug- gested the Air Task Group use an RB-36 instead of the already assigned RB-50, making a total of five B-36's, Task Groups 7.1 and 7.4 suggested | that the RB-36 be rigged up for both control and photo purposes. Finally, on 20 August it was agreed that the ATG would operate four B-36's, The RB~36 would be the primary controller and secondary photog- raphy aircraft, thereby eliminating the need for a separate controller B36, One B-36 would be the primary sempler; one would have the primary mission of sampling and secondary mission of back-up controller; and one would operate solely for effects information. troller was used on only one shot (KOON). The sampler back-up con- LASL wanted samples at 55,000 feet true altitude, which was beyond the capability of F-84G's. There- fore, the two featherweight B-36's were scheduled to obtain samples at 55,000 feet, In addition to the B-36 controllers and samplers, fifteen F-84's were scheduled for particulate and gas sampling; three C-54's for photography; and seven H-19's for ground sample recovery.

BEST AVAILABLE COPY HIGH ALTITUDE SUIT REQUIREMENTS Upon receipt of high altitude operating requirements for B-36 and F-8, aircreft,as outlined in JIF SEVEN-Operations Order 1-53, the use of the T-l High Altitude Suit for crew members was immediately investigated.
