Over the international waters.
Under the azure sky.
Two unidentified fighter jets, with no markings and transponders off, were hurtling through the sky at a speed of Mach 6.
To escape safely and avoid a high-altitude collision, they could only run for their lives at full speed.
What does Mach 6 mean?
It means traveling 2041.8 meters per second, clocking out at 7350 kilometers per hour.
Though this speed is far from reaching the human-piloted flight speed record of Mach 9.8.

And at such a speed, it's already faster than many of the older missiles.
Of course.
The Fierce Dragon Fighter Jets did not pursue beyond their boundaries.
