Painting a plane is a cool idea and would no doubt be the sickest looking plane on this planet, but it's not the place to be putting BlackCoin community money right now. For example, I'd rather see $10,000 go to some CoinKite push campaign, where we could bulk order terminals and strategically place them in very high traffic areas, pushing not only BlackCoin, but crypto as a whole to the world. (Just one idea of a few where $10,000 could make a good push for BC)
When BlackCoin is at 300K satoshi instead of 30K, then maybe we could start thinking about some paint jobs. Because then it's only going to be "1/10th of the cost" it is right now.
