WOCS SOP

Destin, Atlanta, Panama City and other locations. You're about to be flooded with information and will have plenty of time to study later on. Unless you have an aviation background or a hobbyist, all of the information you could study on aviation would be for rote memorization. Without context or correlation you could be wasting your time on anything but learning how to and why to log flight time.
