 It's not difficult to qualify. So what we need from people who are interested in traveling with us, complete our online application. You need to tell us where you're going from and to when you need to travel. We do need about five days at least to coordinate the first flight because the one thing that we do have to do for everyone who flies with us is we get a physician's release from their doctor. This verifies the need for us, and it also tells us that it's safe for them to fly in a small, unpressurized aircraft.
