It would be nice to ad the Concord to IF. It is a nice plane with a few liveries. Pan Am, Air France, BOAC, Continental Airlines, American Airlines, TWA, Middle East Airlines, Qantas, Air India, Japan Airlines, Sabena, Eastern Airlines, United Airlines, Braniff, Lufthansa, and Air Canada air flyers of the Concord. It would also be neet to have a IF livery also.
