Secrat X-37B shuttle-like spaceplane was easy to spot

Well, that was easy, and also answers the question I had about how the U.S. military intended to keep the mission secret, given how easy the ISS, satellites and just about everything else are to spot. It's beginning to look like making the mission a classified one was just a decision based on convenience than anything particularly secret it might be doing. Well, except for what it has in the cargo hold. That can't be spotted by amateur astronomers.
The group that spotted it is pretty impressive, however: apparently they've spotted every single object launched by anyone over the past five years, including this one. Not bad at all.
