From the end of the article:
Despite its potential, significant engineering challenges must be resolved before hypersonic travel becomes a practical reality.Extreme heat and pressure at Mach 16 require advanced thermal protection systems to prevent aircraft from breaking apart.
Materials capable of withstanding these conditions must be developed,
and cooling mechanisms must be perfected to ensure structural integrity during flight.
Another major hurdle is stability and control. Researchers must refine the technology further to ensure that hypersonic engines remain stable across various speed ranges.
developing cost-effective aircraft that can safely operate at these speeds remains a significant challenge.
If the technology proves too expensive, commercial adoption could be delayed for decades.
It would make the world an even smaller place if it becomes available for commercial flight.
Therefore this article is crap and does not belong here!
