The first era wasn't known as such until the advent of FSDS when there became a big difference in the possiblities that could be implemented in FS.  These aircraft, although currently planned for FSDS recreation, were designed in a time long before FSDS when the very design of a concept determined how well it could be replicated in flightsim,...due solely to the strict limits of design tools used to create them, Aircraft Factory 99.  Even though these aircraft are no longer created with AF99, Era I continues as I accumulate new idea's for re-releasing these older aircraft.
