Yes machineman9 I know that it is just keep trying, but I just want to hear about their was some difference I could find. Thanks for your reply snoopy51
A lot of the currently available 'FSX aircraft' are existing FS9 models updated to work in FSX. These could be converted back to work in FS9 but I don't see the point. Aircraft created specifically for FSX with the latest features will not be compatible with FS9.
