forest cover, and the aircraft in which the infrared equipment was installed made 

 repeated flights over the fire targets. 



Analysis of the measurement data indicated that small (2-ft. diameter) smoke- 

 less fires located in the coniferous forests selected can produce detectable signals 

 at least 70% of the time on the TIA radiometric equipment used. 



None of these fires could be seen at any time by observers in aircraft, nor 

 could they be seen from lookout towers. 



This 1962 experiment provided only an assessment of possibilities. Further 

 tests would be required to assess the obstacles to practical application.
