"The C-54 display is quite remarkable for a World War II-vintage four-engined heavy transport (well, heavy for its time, anyway!). It includes a low pass with the two starboard engines shut down. The pilot goes on to loop the plane later in the show - something I've never seen done by any other aircraft that large and heavy."
