    Description

    With the recent use of airplane patrol to discover fires it has become important to review what is known about the visibility of smoke and to study any new theories or applications of present knowledge that are suggested, Airplane patrol is expensive on an hourly basis, The time available for the observer to see a smoke before he has passed too far beyond it is short. For these two reasons he and the pilot should know how to fly so that any smoke in a certain place will be in the most favorable position to be seen by them.
