ALTERNATIVE NUMBER ONE. THEY WOULD RECOMMEND UTILIZATION
OF LOW ALTITUDE LIGHT AIRCRAFT EQUIPPED WITH INFRARED (IR)
FILM TO PHOTOGRAPH THE AREA IN QUESTION. IT WOULD BE NECESSARY
TO HAVE SUCH AN AIRCRAFT MANNED BY PERSONS CAPABLE OF OPERATING
THE REQUIRED CAMERA EQUIPMENT. SUCH PERSONNEL COULD POSSIBLY
BE SUPPLIED BY STRATEGIC AIR COMMAND (SAC); UNITED STATES AIR
FORCE INTELLIGNECE, OR AEROSPACE CARTOGRAPHIC AND GEODETIC
SERVICE, TOPEKA, KANSAS. NASA HAS NO SUCH AIRCRAFT, BUT ONE
COULD BE RENTED OR COULD POSSIBLY BE OBTAINED FROM ONE OF THE
AFOREMENTIONED AGENCIES. IT IS NOT KNOWN WHETHER ANY OF THESE
AGENCIES CURRENTLY HAVE APPROPRIATE THERMAL IR SCANNERS WHICH
WOULD BE NECESSARY FOR DETECTING BURIED OBJECTS THROUGH EARTH
SCARS, THAT IS , DISTURB SOIL. HOWEVER, IT IS BELIEVED THAT
THERMAL IR SCANNERS WOULD HAVE PRACTICALLY NO VALUE IN
ACCOMPLISHING THE OBJECTIVE, PARTICULARLY IF THE AREA IN
QUESTION IS SNOW COVERED.
ALTERNATIVE NUMBER TWO. IT IS POSSIBLE TO USE IR
CAMERAS AND OR THERMAL IR SCANNERS WITH HIGH ALTITUDE AIRCRAFT
