I don't know really. I had a big fiasco with my last crew chief; simple stuff would break down like lightbulbs would be out for a good few missions at a time, or my CMS programs would be out of whack. When you're coming in for a runway attack and your chaff and flare dispensers are quiet, well, let's just say he's lucky his head is still on his neck.
I guess this is his way of getting back to me. I suspect my current crew chief to be buddies with him which is really the only way I can explain the extended downtime. I've put in a request for a different guy, but you know how slow these things take.
For now, I'm just enjoying a little R&R.
