Wave drag/Shock waves

This applies to all transonic and supersonic planes. I noticed that as I approach the speed of sound, I didn’t face any resistance. This means that I don’t face wave drags. This led to some insane super-cruise speeds. So I think this type of drag should be in the game, as you go above speed of sound, the resistance would drop again and the flight would act like normal.

This is something I don’t think many people know about. I feel like it could be easily implemented… but I honestly don’t mind either way.
