I am a librarian at a University with a strong military tradition and a very strong ROTC program. Once a year the ROTC cadets get to practice with/experience what it is like to be around/in/on a real Blackhawk helicopter. They fly right over the library and land on the lacrosse field behind the building. It is an awesome sight to see and I get choked up every stinking time.
Here they are flying over the first time
