Archaeopter
"Your logic and... persevereance... are compelling. Request granted. Archaeocopter deployment approved."
- – Magos Dominus Bartolomus finally accepting the skitarii's requests for flyers after long negotiations
The Archaeopter is the first exclusive Adeptus Mechanicus flyer, and the only one for now in 8th Ed. For what we know now, it comes in transport, gunship and bomber varieties, though more info will be released in the future. It's ornithopter design is quite unique in the Imperium of Man in comparison to many of the boxy designs of flyers of the Space Marines or the Guard, and is yet another Dune reference in 40k.
