I was searching yesterday for the A300B4 and as i was looking in wikipedia i found that only four A300s are preserved today. One of them ex-N11984 Continental Airlines Airbus A300B4 preserved in South Korea as a night flight restaurant. I don't know if the plane is on the ground and simple they call it like that or is actually flying, but I believe that is a characteristic of one Executive Airline. Small flights 2-2,5h trip with a luxury Jet, over a place where rich people can enjoy their meal or have a drink at 30000ft!!!
