On 20 November in response to a request from AFSWC, Al Graves sent a letter to Mr. Hertford with info for ALO and AFSWC on sampler aircraft. He stated that both Livermore and LASL had looked at the requirements and agreed that Cu six operational B57 aircraft including a controller are required per shot. With the assumptions that provision should be made for sampling two shots on each of the two successive days and that the possibility exists that operations requiring such samp | ings may be conducted simultaneously at two geographically distinct locations, the understanding is that all of this is equivalent to a request for 24 aircraft, of which 10 have the high altitude capability of the B57Ds. LASL is procuring sufficient wing tanks to equip 24 aircraft plus one set of spares. Also on 20 November, Ba tzel of Livermore makes the Livermore sampling requirements known as a requirement for B57 aircraft on all shots proposed by Livermore at a 13 November meeting and on the projected Hawaiian open sea operation. The gas sampling equipment should include "squeegee" compressors (not engine compressors) on all aircraft and LRL- designed isokinetic flow wing probes used in Hardtack | on Bs Cs and Es. Ds should have fuselage probes. i g #1802, Meetin NG. 21 November L 961 : ers had ha fitters and th e operating engine It was discussed that the pipe ed a strike the former group had establish and NTS the at ent eem agr dis a other unii ons have refused picket line which certain to cross.
