OT-Space ship designers use SE images.

[Randallw]

I was reading an article about the private spaceship industry and they had the attached picture. It sure looks to me like whoever is designing their spaceships uses the same software as SE modders. The article says it is based on Boeings Bird of Prey (no not the klingon one, the stealth prototype) although it doesn't appear to have the identifying wings.

There's a rough correlation.
