The Mitch Pines mentioned in the article was a member of LIARS Tripoli section (and the North Shore Section NAR section) until at least the mid 1990s. He had a website, but hadn't been updated in years last I checked.

The "Doctor" Morrow, or perhaps one of his sons, was also a member.

Mitch showed me his Coaster literature, and brought a few Coaster kits to launches. He flew a few with FSI motors, as I recall.
