The first version of the grid search, it's main purpose was to find the POI's we had to drop, but is wasn't battery effective, leading to a drone crash due to low battery.

Improving on the original design, the second version used a lower altitude during the grid search and went up to 100 feet instead of the 75 feet of the original grid search, it also lowered altitude during the return to launch, making landing easier and saving more battery in the process.

This was the mission plan that utilized the dropping mechanism, it used a easy to change mission that utilized a loitor so that the pilot can manually drop the bottle, though it could be changed to be automatic.
