The disabled Night Corsair (the one with the radome, allegedly) comes in for a landing on Vella La Cava... Except that it's missing the radome. After it lands, the camera zooms in on the plane, and now it mysteriously sports the all-important radome. Talk about yer "ghost readout"! :-)
This episode marks the arrival of Nurse Samantha Greene (Genral Moore's daughter using her mother's maiden name) and Pappy's Lambs a group of new nurses assigned to the hospital on Vella La Cava.
