 A helicopter medevac, also known as dust-off, it's a vehicle where we can facilitate patient transfers from lower levels of care to higher levels of care in a much faster time frame than ground medevac traditionally could achieve. Usually what we do is we bring out units, we like to do it in person around the actual helicopter because talking about it in like a hangar or something like that doesn't facilitate the training as well. And what we will do is talk the group through aviation procedures, we talk about what our capabilities are, we talk about how to be safe around the aircraft, we answer any questions they may have to make people feel like they can be comfortable around the aircraft. This specific training scenario and location offer us a chance to do things like rooftop hoist and work with units that don't normally get to work with dust-off units. Our OCTs specifically are flight medics so they already are experienced around the aircrafts. They know how to drive the scenarios that offer realism for us and give us something to build our training off of.
