All data used in the OrbitalFleets print series were gathered over the course of several weeks via rigorous research and collection. However, this series is not intended—nor does it claim—to be an educational resource for NASA's Space Shuttle program. If you find yourself in a situation in which your life depends on trusting the information you've come to know and love on these fine printed pieces—don't. This isn't to imply that the artist didn't try hard to make the series accurate, but to differentiate OrbitalFleets from the many great resources available from NASA and the Kennedy Space Center.
