Clouds and Cargo

Forecast wind and crate weight change altitude at each gate. Spend limited fuel on flaps, and fill cargo rows to unload and refuel. Select a cargo column then Load & fly. Gate altitude equals current altitude minus crate weight plus wind. Flap raises altitude by two, up to ceiling six, and costs one fuel. Missed bands cost one hull. Full cargo rows restore one fuel and one hull only if you survived the gate. Undo restores cargo, fuel and altitude. Deliver all eight gates with hull remaining.
