Up until now, the market had already assimilated the impact of anti-gravity technology.
In fact, the development of anti-gravity technology had not had as strong an impact on the civilian aviation market as one might have imagined, at least not as significant as expected.
For instance, commercial aircraft had hardly been affected at all.
Anti-gravity flying vehicles were extremely large, and the consumption for each flight was also very high. Moreover, the main reason was that anti-gravity flying vehicles were more adept at vertical takeoff and landing; their horizontal flying speed was not fast and could not possibly catch up with the various turbine-powered aircraft specifically designed for aerodynamics, because the main obstacle to an aircraft's horizontal speed was air resistance, not gravity.
