Maybe gone, but not forgotten
I'm not talking about the SFWS birds. I'm talking specifically about the blue one(s) you posted a picture of. 160945 and 160949. They were a good deal wasted on those that didn't know what they had.
Short version, the VS guys handed them off to HSL and were used as Opfor for LSF training. But there was only one guy in HSL land that was qualified to fly it until two just-out-of-VT-land guys showed up, both Stan IPs and one the assistant model manager (and the other who just needed a quick flight with the TW5 model manager to make him an ANI). Cost-wise, they were a fantastic resource and good-deal-wise, they were awesome to have, but there weren't enough people to fly them and the two VT guys also had DH jobs and had to deploy. Fast-forward a year and they went away. There's debate about why, but when you don't fly your allocation, it's hard to justify allocating them to someone that doesn't use them.
And even when they were going away, I managed to setup a way that the two of us could fly them both out to San Diego for drop-off, and even that got killed by an individual (a JO, no less!!!) who had no imagination or any real understanding of things T-34C.
Yes, I'm still bitter, as is the other guy.
