 So exactly a hundred years ago there the first airy feeling happened and it was just between two biplanes and what they did was they just passed a hose between the two airplanes and so so it is exciting here for us at Sioux City because we can display exactly what we do every day and we'll be doing this in different landmarks around the midwest and showing people exactly what we do. Yeah so we fly the KC-135 it was originally built in the 1960s and we still maintain them to today and there's no projection of retirement right now. Basic crew for this KC-135 is two pilots and one boom operator. We're going to take three pilots with us just to help us with timing and and navigation. And so we watched F-16s when we were a kid and by the time it was my turn to get into the military we were flying KC-135s here and so I became a crew chief here and ended up getting my private pilot certificate and then applied to be a pilot here.
