 What we're doing today is some experiments to look at actually measuring the performance of the air drops. The water drops that come from the aircraft and things like the spread pattern, the coverage, the amount of water, so that we can try to understand the relative effectiveness in terms of wetting the ground and helping to control fires. We're measuring the air drops in a series of hundreds of cups that are laid out and they capture the water from the aircraft drop and then we go through and retrieve those cups and measure the weight of every single one. From the drops already we're already seeing the nature of the water column as it drops. The heavier water droplets first followed by a wider area of mist and that's all really important for wetting the ground to suppress the bushfires and cool them down. Different types of drops might have different effectiveness and different purpose depending on how the fire is burning and where.
