Because at this altitude, the air pressure is already very low, and the air is thin, which will have a negative impact on the aircraft engine performance and aircraft aerodynamic performance, reduce the aircraft's gravity and drag, reduce acceleration and deceleration performance, and worsen the aircraft's stability and maneuverability. As long as you are not careful, it will cause dangerous situations such as stall spiral and pitch swing, and in extreme cases, it will even cause mid-air parking.
Therefore, fighter jets will only fly to such high altitudes unless testing aircraft performance or when it is extremely necessary. Otherwise, fighter jets usually operate at altitudes below seven thousand meters.
This is just like fighter jets will not fly at supersonic speeds under normal circumstances. Whether it is supersonic flight or ultra-high altitude flight, the damage to the fighter itself is still quite large.
But this time, George pulled Yang Jing up with him, and he had to let the BOSS feel the top speed and altitude, so George first flew at a speed of Mach 2, and then reached an altitude of more than 15,000 meters.
George's actions really won Yang Jing's satisfaction and praise. Yang Jing couldn't help but praise him. Whether it was the rapid flight just now or the ultra-high altitude flight now, Yang Jing had never felt it before. Even if he had an extremely powerful holy ring, the holy ring could only help him show off, but it definitely couldn't help him fly...
After feeling the altitude and speed, George began to control the fighter plane to descend. It had actually been less than twenty minutes since takeoff, but in these twenty minutes, at least $1,000 worth of aviation fuel had been burned.
A fighter jet is an absolute fuel guzzler when flying at supersonic speed!
