There has been a number of AN-124 in/out YMML over the past month, and I think you'll find there may be a few more.

If I'm not mistaken, they're transporting products necessary for Qantas' 737-300 conversions (Pax 733 - Freight 733 [AaE]). Not sure about that though, another FT member may be able to help out with that

Photo available here for those interested. Amazing aircraft, that's for sure.

Interesting post hobarthoney!
