4. We are obviously concerned about the safety of the aircraft and will thoroughly review all the information before making final recommondatlons. For the moment, however, we do not believe that thero is sufficient concorn totand-down and would propose that if the weather clears that we should continue to operateumber of precautions such as maintaining very high altitude and some adjustment of our flight routes. We will make further recommendations concerning any other adjustments in tho program that-may be required when our analysis is complete.

NOTE FOR: The Director
I justook at some of the COHINT traffic relating to Friday night's Mission andew quotes might bo usedight conversation on this subject develops.
Apparently most of tho communications between the Regimental Controller at Phuc Yen airfield and the Battalion Commander of one of thoites was The Battalion Commander had been ordered to fire when the aircraft was. from the site. Tlio two argued about whether that was beyond theof theystem. He did actually fire when the aircraft2 miles away. The Batalion Commander said that firingistance5 miles and at an altitudo4 feet was "unrealistic and too far and highuccessful launch." The Controller complained that "One missile was not enough." The conversation then turnedore congenial mood, and the Controller congratulated the Battalion on their being the "first unit to be able to pick it up and launch." The Battalion Commandor replied, "There is tho matter of my having experience already. If it continues and comes in again, I'll intercept it." The Regimental Controller then left. Tho Battalion Commander continuod, "Perhaps if we launch at it it will leave, but our missiles are too slow."
