Depending on what you do I think you shuffle between HQ and the airport... As per details beyond that, I think you get to do a lot of revisions, mailbox stuff, basically anything anyone who was an aviation intern did more or less. I think you might get to sit through a recurrent ground too. Could be a slightly more exciting process with everything going on around here. One of my former students was an intern last year and got to do a variety of things other than the run of the mill and he had good time.
