I have noticed that the only way to have someone else on a piloted ship is with ladders, so I propose the idea of passenger seats. It could be a multiblock item that you pay for like anything else, but the passenger can’t pilot the ship. Just a suggestion that I think would help and increase communication between players.
Multiple passengers can already be on a ship if they’re on when it’s piloted.
Not with me I was trying to fly a friend and he kept falling
Make sure that they’re on when you pilot. If it still doesn’t work, try a bigger ship.
