This nevada, you can walk inside of it by jumping into the Door gap (open the door first, then jump inside)

There is

- Seats inside
- Windows you can look through to outside
- Detailed interior in nearly GTA style, LOW SIZE of txd/dff (mod total: 300kb)
- Fits in GTA atmosphere

It works also fine with multiplayer mods like MTA:SA or SA:MP, you only got to tell other players who wanna enter, that they got to glue inside on the floor, as otherwise they will fall out or stall your plane mid-air or when taking off.

My mods that are enterable are as usual very optimized.
Made with 3DS Max 2017 and txd lowsized + mipmapped while still retaining a good texture quality.
