Unfortunately being ridiculous is not lethal. If you have heard or read a little about some Flight Pro Sim, you wouldn’t think it is just the exact copy of FlightGear, the famous freeware and open-source flight simulator developed since 1996. But that’s the case here.
If their homepage was not horrible enough to refrain you from loosing money, now you know you have a 60 days money back guarantee you should use. Download the original FlightGear for free instead. Spread the word and use FlightGear homepage URL to link about “‘this”, so Google does the rest of the job.
