Safety Recommendation A-67-002
Recommendation
SINCE THE SYSTEM APPEARS TO HOLD PROMISE, IT IS HOPED THAT THE FEDERAL AVIATION AGENCY WILL NOT OVERLOOK THE POSSIBLE MERITS OF THE NORTH AMERICAN SYSTEM.
Safety Issue and Context
IN REPLY TO YOUR LETTER OF DECEMBER 16, 1966, WITH WHICH YOU FORWARDED A COPY OF FAA REPORT NO. ADS-81, "BOMB DETECTION SYSTEM STUDY", DATED OCTOBER 1966, WE AGREE THAT DEVELOPMENT OF THE "CHEMOSENSOR" SHOULD BE CONTINUED SINCE IT OFFERS PROMISE OF BEING A PRACTICAL BOMB DETECTOR. HOWEVER, WE WOULD LIKE TO DIRECT YOUR ATTENTION TO ANOTHER SYSTEM OF DETECTING EXPLOSIVES, ONE THAT APPEARS TO OFFER POTENTIALITIES WORTHY OF CONSIDERATION. THIS IS THE NEUTRON ACTIVATION SYSTEM BEING DEVELOPED BY THE LOS ANGELES DIVISION OF NORTH AMERICAN AVIATION, UNDER THE DIRECTION OF MR. T. E. CARRELL.
