Clarification of rules by Peter Gelman.
Flight: Movement From the Cloud Boards
'A disk starting movement on a Cloud square must note the color of the square first; it may fly to any empty square on the Earth board of the same color, or the other Cloud’s square of the same color if it is empty.'
For example, Red Monkey King is on R-101.
From R-101 Monkey King can fly to all White Earth squares: a1, a3, a5, a7; b2, b4, b6, b8, etc.
Also to White Goblin Cloud square R-100.
So, a player can move piece from his Cloud to opponent territory (5-8 ranks in this example).
