The DC-2

Have you ever heard of McDonnell Douglas DC-2? In Aviation Empire, I called it the money making plane because its profitable on short routes if you haven't reached 1980s. So far, I'm still keeping em' because i'm in 1971 and still trying to troubleshoot my problems with DC-10. They're not making profits for me now but they do make profits for me before. Good luck playing Aviation Empire! Also, I'm playing in Adventure Mode so these tips aren't guaranteed to be successful in Story Mode.
