MEMORANDUM FOR: Deputy Director for Science and Technology

on OXCART Program ifs Used for Speed Record Attempt

he initial look at the problem indicates that two separate and distinct effects would resultow were to be usedpeed record attempt, one resultingross risk to the projected technical time schedule of the program and the other resulting in an immediate gross security compromise. No equipment effectrwould result on the SKYLARKontingency capability) programlready hasomplete set of reworked servos so that none would have to be diverted from SKYLARK aircraft and would only require that the engines, which had been removed during the recentpeed trial deliberations, be reinstalled. However, the flight test support to SKYLARK will be diluted since Lockheed flight test personnel will be concentrating on tho speed run. The support to SKYLARK is in the area of check-out and test of ancillary equipments for SKYLARK, such.as,ingle side band and countermoasure packages,

gross risk to tho projected technicalalluded to above takes into consideration the fact

thats the primary flight tost vehicle.

(seeor roles of the four2 flight testnd, as such, is very heavily instrumented to measure and record flight test results. Any damage to this aircraft, or to consider the ultimate, loss of this aircraft, would seriously retard the progress of the program until another vehicle could be similarly Instrumented. Tho extensive wiring and large number of very closo tolerance sensors installedrc such that it would take approximately two aonths to similarly equip another vehicle in the eventere lost. To risk serious impairment of the program objective solelyropaganda advantage hardly seems justified.
