x 15 is faster then the sr71 blackbird who can only reach a speed of mach 3.2 which is 3 times the speed of sound but the x 15 can reach mach 6.72

What is SR71 auto insurance
The question is not defined to be answered properly A Cessna propeller driven light aircraft is much slower than a 747 But a SR71, the current record holder for speed is also much smaller than a 747
It is √(x15), which can be simplified to approx 3.873*√x.
