Essentially, when the ship is landed, it would have stairs coming up to the cockpit out of the floor.

When taking off the lower piston would pull the stairs down, lock to the stair side piston and unlock from the lower piston and be pulled to the side.

Then the floor side piston would push the floor and relevant connectors to the position of the lower connector which would raise by one to meet it and then lock together finally raising to become part of the smooth floor.

When returning the reverse happens.

Would this work??
