I've been posting a lot about the TR-3 spacecrafts on Facebook and Twitter this week following a photographer's capture of a triangular craft near Wichita, Kansas this past weekend.  In an interesting synchronicity, guess what showed up on NASA's own ISS feed during a spacewalk this past Tuesday?

That's right, a pretty obvious TR-3B made an appearance.  It becomes visible at 1:02, becomes clearer at 1:24 and gives you a great shot of its backside at 1:48.  Look between the station and the Earth, you can't miss it.  One note, this is on NASA's own YouTube channel, so there's zero chance of fakery.
