evolve from a dimensional difference in a new set of strontium sources, that nave been ordered from Oak Ridge, as well as practical field experience with the device during the tests. The ship on wnich the telenetering station for Project 6.11 is to be located has been requested for availability on the West Coast for inspection purposes in mid-July. This inspection is required by the project contractor (Pacific Division, Bendix Aviation Corporation ) to locate the four antennas required. Some modification on tne vessel will probably be required to accomodate these antennas. Tne decision to drop the MOTS stations due to operational difficulties arising in regard to the predicted location of tne Task Force at snot time has removed a major portion of the zolmes and Narver construction required for this project. Project 6.12 nas been dropped since no feasible metaod of accomplisnment could be determined in the limited time available. A new project, Project 6.13 ~ "Measurement of Free-Air Pressures by Rocket Photography", proposed by AFSWP is being considered. The measurement of free-air pressures by means of photographing smoke ‘trails produced by rockets is considered to be both desirable and feasible by the sclentific task group. It is understood that if epproved, tne Naval Ordnance Laboratory will undertake this experiment at an estimated cost of $30,000. It will be necessary for NOL to supply all of tne personnel necessary to conduct this experiment — with the exception of two or three Holmes and Narver personnel who BEST AVAILABLE Copy - 32 - | "
