The first forgotten airline series is a Union de Transports Aériens aka UTA, and yes, it's real. If I don't made this, nobody will know about this.
This plane I made is a F-GEXB in M as combi version, so what is M variant on 747? it's a half passenger and cargo.

Download contains schematic and map.

Note: if you are use Amulet for 1.16.5, you must disable Paste lava, water, and air before place into your world. As this my build are not compatible with Aeroteam's texture pack.

Respect me, do not use my map (including models) for making video content that I really don't like (ex: vs TNT, etc), or I will show up your name in the next post (even you are from where). Only your repaint or showcase are allowed.
