Actually line number 1416 has just been delivered to Cargolux as LX-ECV. Quite why they are getting a 744F when they are also getting 748Fs is interesting.
Did not know that, about time. It will be an expensive airframe to operate considering the D check it will need within 24 months.
The Performance Improvement Package (aka PIP) engine that we hope to certify in the next few weeks is good for 2% fuel burn (I wasn't sure if I could say that, until I saw it in the Everett newspaper ) - Ozark is intended to be on top of that (various weight and drag improvements).
The PIP is less than 2%, and the HST is needed along with the PIP to reach design range (hopefully).
