"Fonts" of the S-IC
New 7/7/09
The "Small
Stuff"
It's fairly easy
to ascertain the general size and shape of the large lettering on the Saturn
V first stage. But just barely visible in many photos are those "ghostly"
tiny letters that mark the various hatches, vents, and what-not on the
stage. In spite of common belief, the "font" was not a common form of
Helvetica but was a letterform that had its roots in the World War II (and
perhaps earlier). This letterform has appeared on close-up photos of Boeing
B-29 bombers (credit Rich Sternbach). This is completely logical given that
the Saturn S-IC stage was also manufactured by Boeing.
The actual shapes
shown here come from photos taken of the Saturn V at Johnson Space Center
soon after its arrival there in 1978 as well as actual measurements taken
from a few remaining traces of the lettering found on that vehicle during
its conservation project in 2004-2005. It appeared on that stage in various
areas in 1", 1.5" and 2" tall sizes. The color was a very bright (nearly
fluorescent) yellow-orange. The letters on the stage were not stencils or
painted on but were individually applied adhesive backed plasticized paper
material. In general, they were applied to the individual stage components
during manufacture of each component before the stage was assembled.
