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
The SR-71 is far faster.
there is a argument currently about this question 1. the sr71 loknee blackbird 2.the x15 nasa first plane in space 3 currrently i dont know the other ones but i will look in to it
What is SR71 auto insurance
The SR-71 Blackbird is 2,193 miles per hour fast or Mach 3, three times faster than the speed of sound.
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.
