Atlas Press Co. was a tool company that manufactured popular brands of metalworking tools from 1920 to the mid-1970s.
 Many of their products received wide coverage in "Popular Mechanics" and "Popular Science" at the time.
SpaceCub was a design project for a homebuilt rocket.
 Between 1993 and 1994, Geoffrey A. Landis proposed that a vehicle designed to launch to the edge of space might be a feasible project for a "personal" spaceship, the equivalent of a Piper Cub for space.
 The insight was that a flight to "only" 100 km would reach the officially-defined edge of space, and even though this is much easier a challenge than an orbital flight, such a suborbital flight would be of excitement to the public, and the pilot would be officially qualified as an astronaut.
 A small group of rocket enthusiasts, computer hobbyists, and science-fiction writers gathered together to do a preliminary design, with the ultimate goal of moving on to building a prototype, with (then) physics student David Burkhead leading the technical effort.
 The vehicle design was discussed in many venues, and presentations on the design progress were given in several conferences, such as the 1995NSS International Space Development Conference, where it attracted considerable popular attention.
 The design was featured in print in places including the December 1994 Popular Mechanics, and the Brazilian popular magazine Istoé.
Popular Mechanics is a classic magazine of popular science and technology.

The Parker Jeanie's Teenie, or JT-1, is a single-seat, single-engine sport aircraft first built in the United States in 1967 and marketed for homebuilding.

 The caption on the cover read, "Build This 'Flying Volkswagen' For Less Than $600!
."
 The cost of materials has increased since the article's publication but the initial popularity of Parker's Jeanie's Teenie was high.
