Earth Pre-Federation Database - Bell Huey 204
	History:
	Rotor-winged aircraft in use on Earth in the late 20th century. One such helicopter craft, owned by Plexicorp in San Francisco, was borrowed by Sulu in 1986 to deliver some acrylic plastic sheeting to the time-traveling Klingon bird-of-prey. Sulu noted that he had flown something similar back in his academy days. The Huey pilot who "loaned" Sulu his ship was played by Tony Edwards.
