"B-51 Mustang" . . . Their guide, Wayne Morgan, pressed pause on the VCR, freeze- framing an image of what appeared to be a sunken airplane.

      "What the hell is that?" asked Morgan as he, Mulder and Scully stared at the screen. Mulder answered first, "it looks like the fuselage of a plane." Immediately following his comment, Scully spoke, surety in her voice. "It's a North American B-51 Mustang."

      Morgan cast her a quick look as did her partner, a slight smile forming on the latter's face. Glancing back at the screen, Morgan remarked in agreement, "it sure does."

      Unable to let Scully's here-to-fore unknown knowledge of older American aircraft pass, Mulder just had to add a comment of his own. "I just got very turned on."

      Scully spared him a lingering glance, but made no comment.

      He hadn't expected her to.
