Available MD11F's
Sorry to do this, but there are at least 4 units available on the open market for sale.
Transmile's 4 MD11F's are currently being remarketed, Aeroflot cargo went belly up a few weeks back and those leased aircraft may be made available for lease, and on top of those ones, there are around 10 that are being parked/stored as airlines try to weather the downturn.
In short, if Avient want MD11F's, they could certainly get hold of some for short, medium or long term.
