Ole ole, looks like it.
It also looks like the green track on the graphic I put together, the western route using a constant magnetic hdg, as suspected, does not match any track which would correlate with the hourly satellite pings.
Actually on second thought I think we still don't have enough data to jump to conclusions. The aaib tracks mark just the two extreme possibilities. There might as well be a constant magnetic heading solution with a higher speed and a more westward heading than the red track. That would end up much closer to the great circle (yellow) solution.
