airplane home has a two piece spiral staircase entry system. The first piece (below)
is securely bolted to the ground. To enter the aircraft you would first walk up the
spiral staircase and stand on the inner platform as the character is doing below. No
part of the below section moves.
From the inner
platform, you would step to the outer platform. The outer platform is connected to
the airplane. There are no "pinch points" between the piece that moves and
the piece that is bolted to the ground.
Put the two
pieces together, add the airplane on top and you will be spiraling up through what used to
be the left wheel well.
