Contracted Army ROTC cadets at Clemson University will fly in military helicopters Saturday, April 6, as part of the spring semester field training exercise. The helicopters will begin picking up cadets for the first of several trips at 4:30 p.m. at Fant’s Grove. More than 40 cadets will learn how to establish a landing zone, board a helicopter with combat equipment and exit air crafts to authorize security. They will fly to the field near Jervey Athletic Center. The public is invited to observe the exercise.
