Frequently Asked Questions
Have We Gone Mach 10?
While Mach 10 remains a primarily theoretical speed bracket for controlled, sustained flight, significant strides have been made in hypersonic technology. The NASA X-43 briefly achieved speeds near Mach 9.6, but controlled, sustained Mach 10 flight is yet to be achieved by current standards.
Can A Fighter Jet Outrun A Bullet?
Fighter jets generally cannot outrun a bullet in close proximity, as bullets travel at extremely high speeds (typically faster than Mach 2.5). However, over larger distances, fighter jets can maneuver and eventually evade ground-based weapons or slower projectiles.
Which Country Has The Best Fighter Jets?
Determining the “best” fighter jet is subjective and depends on various metrics, including speed, agility, technology, and specific mission requirements. The United States, Russia, and China are often in the conversation due to their advanced aerospace technology and extensive air force capabilities.
