This means that you should never have to adjust them.

They have a tremendous advantage over conventional clocks, they are always right! When working properly, radio controlled clocks always display the correct time, down to the exact second. These clocks are sold in all forms: as wall clocks, desk clocks, travel alarms, and wristwatches. How They Workīy now, you have probably seen or own a radio controlled clock.

If I did, I would have visited the actual artifact and taken copious notes. I did not live in the Washington, DC area at the time. Essentially, this was the only resource I used, occasionally supplemented by photos found online. This document is similar in some ways to the kind of manual you might find for a car in that it contains many drawings of individual components and their placement, plumbing and wiring diagrams, and various other interesting elements that are invaluable to a modeler wishing to build a Friendship 7 model.

But the most important resource (beyond the actual vehicle, located at the Smithsonian National Air and Space Museum in Washington, DC) is the NASA Project Mercury Familiarization Manual (NASA SEDR 104), November 1961. Oddly, there is not much data on Friendship 7 readily available online. Also, Glenn peppered the interior with all sorts of notes taped to the instrument panel and made various marks applied with a pen - I thought these would be fun aspects to reproduce. I selected this subject because of its historical significance, and chose a post-flight configuration because of the opportunity to explore weathering and distressing techniques. For my collection, I built a representation of John Glenn’s Friendship 7 as it appeared shortly after reentry. In the end, however, I ended up only using a few kit parts: the outer hull, the forward recovery compartment hull piece, the backshell piece, parts of the seat, and a section of the kit’s aft bulkhead part. Still, it is a marvelous kit to work from. The interior arrangement that is provided is generic it would have to be for simplicity sake in that each Mercury had a different capsule arrangement. It lacks, for instance, the forward bulkhead with hatch, helium tanks, tape recorder, interior hull details, and other parts. A major drawback is the model’s lack of interior detail. An astronaut figure is included, cast in vinyl, and is of excellent quality. The escape tower parts are molded in red. The instrument panel parts are cast in a hard clear plastic, which is a nice touch for those interested in back-lighting the dial faces and switches. The outer hull, with the exception of the hatch, is molded in black, while most of the interior parts are molded in light gray.

In terms of a review, the MRC/Atomic City kit is generally well produced. As such, it lends itself well to being represented in kit form at a larger scale, and 1/12 is ideal. The Mercury capsule is a small vehicle, essentially a spacecraft built around a man. Other kits, some of which were produced in the 1960s and 1970s, are in smaller scales and are of relatively poor quality. I am thankful that a model kit of this historic subject in this scale is available. About ten years ago, I built Atomic City’s 1/12 Mercury kit.
