Details of the LRL project Hobo are contained in other notes and let me add here that Hobo was a series of high explosive shots done in tuff in the Area As 12 tunnel E£.03. These shots were necessary for comparison with the project Cowboy shots done in salt to study decoupling as the Hobo shots were to study decoupling. A letter from the Test Director, Mr. Myron Knapp, dated 15 April, /7GO documents the fact that the Hobo series which consisted of four high explosive shots was completed by this date. Logan was the name given to certain activities during 1959 and 1960 which involved reentry, drilling and sampling and study of samples from the Logan event which was done prior to the moratorium. s l : Air Force Headquarters ateg ic Air Command to A 15 April TWX from Str among into the Eniwetok lagoon ches in un la S LA AT d nne pla :the addressing Eniw etok impact favors transfer of the rs te ar qu ad He C SA other places. that this is t of the PMR and feels par as D DO the o t C om the AE | | f i | | ! area fr ATLASES. e FY y d a h c a Z m r a * .
