There are plenty of things to 'spy' on there. It may or may not have been the airport itself. Perhaps they were 'spying' on something more specific like a particular flight, plane (not necessarily a commercial airliner), routine/process...
Also, don't foget to check for TFRs near campus right before you fly. If there is an event (game) at the stadium, you can't fly within 3 miles of it, starting 60mins before the event and lasting until 60mins after the event is over.
Bottom line...
