First of all I would like to say a huge thank you to mainly Blizzard and Mikjaw for helping me with this mod. I would also like to say thank you to everyone else who helped me make it in the subnautica modding discord server. I would also like to thank Shoob (Shirubafoxy) for creating an excellent voice for this vehicle. 

This mod now requires Aircraftlib.

How to use this mod: 
F to toggle flight and agility mode
Agility mode is similar to seamoth except holding space will let you glide
Flight mode has high speed but low agility and holding space will let you do vertical takeoffs

The Alterra Wraith is a newly developed single-seater aircraft, that can also function as a submersible. It is the first Alterra aircraft to ever be usable as a submersible. It is also currently the most used single-seater general aviation aircraft developed by Alterra.
It features:
- Two-speed flight controls which double as submersible controls
- Variable airfoil to ensure stability when in air or water
- Automatic landing gear functionality
- VTOL functionality
- Onboard AI
Advice for pilots:
- Low thrust engine mode will enable agile movements when not flying
- High thrust engine mode is optimized for flight, and will not allow you to 'strafe' sideways
- Base package is not designed for deep sea use; upgrade modules are required for that
Ratings:
- Top Speed Low Thrust: 13m/s
- Top Speed High Thrust: 60m/s
- Max Acceleration: 6m/s/s
