What is the method called when there is no vertical object to use for a bankshot?

The method referred to when there is no vertical object available for a bankshot is known as the raindown method. This technique is used primarily in scenarios where firefighters need to apply water from above to a fire or an area without the benefit of ricochet or deflection off a vertical surface.

In situations without vertical cover, the raindown method allows the operator to create an effective water pattern by directing the stream from a height at a specific angle. This technique takes advantage of gravity to distribute water effectively over a targeted area, ensuring coverage while minimizing the risks associated with achieving the necessary reach to extinguish flames or cool down hotspots.

Other methods such as direct throw, overhand, or sidearm involve different techniques and may rely on the presence of structures or vertical elements to enhance their effectiveness, which is not applicable in this scenario when such elements are absent.
