//***  This program was written to use while conducting aerial     ***
//***  surveys of salmon migration in rivers and near shore areas. ***
//***  A primary objective was to create an application that could ***
//***  be used with minimal visual contact w/the device. This will ***
//***  1) minimize the possibility of air sickness, and 2) maximize***
//***  the amount of time that the observer can spend observing    ***
//***  events outside of the aircraft.                             ***
//***  *********************************************************** ***
//***  The application was written using the SuperWaba toolset     ***
//***  developed by Guilherme Hazan and his fine staff at          ***
//***  Superwaba, Ltd. Superwaba is a proprietary development      ***
//***  environment based in part on the Waba development           ***
//***  environment developed by WabaSoft, Inc.                     ***                         ***
