Do we have a track on where 747-200F ER-BAT happens to be?
First, let me say your post was, as usual, a joy to read.
I'm feeling a little deja-vu, but in going back through ADSBExchange, I have a very-clear trace with lots of readings of the last say 2 hours of her flight on January 30 of this year from FL370 over Banda Aceh descending southeast-bound into,,,CGK!! Is that where she has been all this time? On the one hand, that feels like news; on the other hand, I feel like maybe I already knew that she was being worked on at GMF AeroAsia, but had forgotten it. Weird. I really need to do a little spreadsheet of these aircraft and what they're up to. Anyway, I think that's where she has been for nearly 2 months, so maybe we will see her back in action shortly.
In the month before that, there's a fair amount of activity showing her almost-daily running around to and from Delhi, to China, Singapore, the Middle East, etc. So the fact that this all dried up after a trip to CGK suggests that we should be looking for her around the GMF AeroAsia hangars.
I noticed that EW-465TQ doesn't exactly look freshly-painted, but she does look like maybe she had a bath while at Jakarta. And a nice photo from yesterday of her landing in SGN (on another site) shows the word Cargo has been removed in the last 6 months, retaining the TransAviaExport lettering. She's been doing Moscow-Delhi and now it looks like back to Moscow, although a bit hard to tell. Gotta wonder whether that's vaccine-related given that I think Sputnik V is now being produced by a manufacturer in India. Turns out the Russians apparently had a winner in that vaccine very early on, which makes sense, actually.* It's a little too bad that they couldn't ramp it as fast as some other players, because Russia's willingness to just throw it out there with confidence that it wasn't some strange magical thing that needed to be tested out the butt for safety but rather a standard vaccine construction about which the only real question was going to be effectiveness, and it turns out it works very well. Because they will use it to project influence in developing nations as well as to help their own people, they are interested in a huge ramp-up, and have enlisted India in the manufacturing, because India has big contract vaccine manufacturers and finishers. Maybe coincidence; it's not like the only trade between the two is vaccines, but if this turns into a regular gig for that aircraft, maybe it's related.
*Since I have some tangential involvement in this stuff, I would mention (if anyone cares) that the Russian scientists did something smart that Oxford/AstraZenica didn't do. Both Sputnik and Oxford -- and J&J -- use a harmless inactivated adenovirus to transmit the "code" of just the spike protein of the Covid virus to teach the body to neutralize it fast. The Russians decided to use a different vector adenovirus in the second dose. That is, Dose 1 uses one harmless vector virus but Dose 2 uses a different one. That turns out to be smart because some are pinning the disappointing performance of the Oxford vaccine on the theory that the body ends up being primed by the first dose to neutralize Oxford's vector virus, when it comes in the second dose, before it can fully boost training the body to hit the Covid spike protein, so the booster effect of the second dose is constrained. The data on Sputnik suggests that the second dose is a big boost, which tends to validate the theory about the Oxford vaccine. It also suggests that giving a second dose of the J&J "one dose" vaccine, which is currently being studied as a possibility to make that vaccine perform better, probably will be underwhelming for the same reason that Shot 2 of Oxford was -- and why Shot 2 of Sputnik had a strong effect.
