A Nova Aerospace Corporation NAC-120 has crashed in the Swiss Alps after a test flight. More information will be released later. In this time period, the search team will find the wreckage of the aircraft. NAC aircraft orders will be on hold until we find the cause of the crash.
We still have no update and the search team has not yet found the wreckage
We now have the preliminary report from the responders:
On a routine post-modification test flight over the Swiss Alps, an NAC-120 prototype crashed into mountainous terrain, killing everyone on board. Preliminary evidence suggests the aircraft entered an aerodynamic stall while conducting high-altitude handling tests. Investigators are focusing on whether the crew was able to recognize and recover from the stall in time, or if a flaw in the aircraft’s stall warning or flight control systems contributed to the accident.

Probable Cause (Preliminary):
Loss of control following an unrecoverable aerodynamic stall during a certification test, with the exact reason for the unsuccessful recovery remaining under investigation. This fictional accident ultimately leads Nova Aerospace Corporation to redesign the NAC-120’s flight-control system and revise its stall recovery procedures before the aircraft returns to flight testing.
