The X-15 Rocket Plane primarily flew in the mesosphere and the lower part of the thermosphere, reaching altitudes of about 50 miles (80 kilometers) and beyond. This region is above the troposphere and stratosphere, where the atmosphere becomes increasingly thin. The X-15's flights were significant for gathering data on high-altitude flight and space travel.
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
It is √(x15), which can be simplified to approx 3.873*√x.
There probably are no human-constructed aircraft that can fly within the atmosphere at Mach 23. The official record-holder of the fasted manned aircraft speed of Mach 6.72 (4,520 mph or 7,274 km/h) is the rocket-powered X15. An amazing fact is that the record has stood since 1963.

the answer is 6.72866666 recurring
15 multiplied by 15 is 225.
its 19 X15/100 = 2.85
240 square feet
The GCF is 3.
For this size pool, about 4,862.3 gallons.
The x-15 can fly at 4520 mph
