In an announcement posted by DTG spokesman Cryss in Avsims Dovetail Games Forum it was stated that Flight School would no longer be available for purchace and download on steam .
The announcement was as follows :
Our goals with Flight School were twofold: to create an entry level sim for people new to the hobby and to implement technical functionality to build upon in the future. Now, we have expanded our goals for our upcoming simulator, a platform we plan to expand upon and support for years to come.
We will still retain the ethos of introducing beginners to the hobby, but without compromising on the depth and complexity demanded by more experienced flyers by implementing a much clearer curve to mastery in our upcoming sim. With this in mind, we have made the decision to retire Flight School. The sim and all of your saved data will remain in your Steam library, however it will no longer be available for purchase.
We will have more announcements about our upcoming sim in the following weeks as well as something special for existing Flight School owners to thank you for your continuous support.
