There were only six space shuttle orbiters. There was also Pathfinder.

In July of 2017, I had the opportunity to visit the US Space & Rocket Center in Hunstville, Alabama -- home of Pathfinder, a replica space shuttle orbiter with a unique heritage, and an important part of the space shuttle program in its own right.

In this video, I explore the history of Pathfinder and the early testing stages of the orbiter program.

Update, as posted on the IDU Facebook page:

So, in my video about Pathfinder, the Space Shuttle mock up (kind of) at the US Space & Rocket Center in Huntsville AL, I said that Pathfinder was the “only full-size Shuttle on display in full stack configuration”. This is not true, as I totally forgot about the replica of Discovery at Space World Japan, which is unfortunately planned to close at the end of this year. I hope the shuttle finds a new and awesome home.
