Microsoft Flight was DOA. It was never designed as a true flight simulator for starters, and second it lacked any real support from 3rd party developers to move it to the next level.
In July 2012, Microsoft ceased development of the game permanently to re-align its “long-term goals and development plans.” On July 25, 2012, Microsoft announced it had cancelled further development of Microsoft Flight, claiming that this was part of “the natural ebb and flow” of application management.
On July 3, 2014, Microsoft announced that Flight was scheduled to be grounded on October 14, 2014,at which time the multiplayer servers were shut down. This affected online features, such as multiplayer and aerocaches; the single-player experience remained largely intact.
