The environment surrounding jet airplanes in SL may be severe. The vehicle isn’t necessities in SL. In addition many of vehicles jump into the land of another person by Lag. When it was jumped into a vehicle, how do the inhabitants feel it? Therefore, we have various limitation for the movement by the vehicle.
The mainstream of the airplane in SL seems to be a propeller airplane somehow or other. There are place some that the flight by jet airplane is prohibited. And I am advised about the flight by propeller airplane indirectly.
I don’t know why seems to be it.
As for me, both the new thing and the old thing like both. Is there the regulation by the form of the airplane in mainland? I think that there is not the regulation…
