In Mad Zeppelin, you're a Traitor trying to throw cargo off of the airship Nostria to your black-market compatriots on the ground. At the beginning of the turn, the current first player throws three dice, which shows what color of Traitors can throw cargo overboard. (The idea is that the dice show the "wind direction," which would be more plausible if the winds weren't capable of blowing north, south, and west at the same time.) So, on any given turn, a Traitor might or might not be able to throw cargo overboard, depending on the colors showing on the dice.
This is well and good until you get to the Crate of Alcohol cargo card; it says that "This card is not thrown overboard." Does that mean that a Traitor can play the Crate of Alcohol even if the wind isn't in their favor? The rules themselves assume that all cargo cards are "thrown overboard," so it's a bit confusing.
A second thought: if playing the Crate of Alcohol doesn't count as being thrown overboard, does that mean you can also play a second cargo card during that Traitor's turn?
