Currently we have:
- Stairs truck (it has a roof and is also attached to the plane)
- stairs obj (smaller stair object which IRL is mainly used for maintenance purposes
My new suggestion is a Roofless Jetstair used by commercial aircraft.
Additionally, it would be nice to not only have it as an OBJ, but also a functional ground service. Perhaps when it's sunny, the roofless stairs attach to the plane and when it's raining/snowing, the current ones.
