It's a good video - in that despite the scarey hype of "In the Unstoppable Hypersonics" some things might be true, but not for the entire trip.... and the limitations of the real world. e.g. Tungsten is remarkable for its robustness, especially the fact that it has the highest melting point of all known elements, melting at 3,422 °C (6,192 °F; 3,695 K). It also has the highest boiling point, at 5,930 °C . - and - calcium oxide has a boiling point at 2,850 °C - I have vaporised both - turned them into gasses..... I mean this is the top of the mineral heap... in terms of melting points... Everything else doesn't stand a chance...... Soft calcium oxide bricks make excellent blast furnace lining bricks.. molten steel sloshes around against them at 1500*C - doesn't affect them..... Hypersonic temperatures in thick lower atmosphere - temperature, density, velocity, are much much higher that that

@Life_N_Times_of_Shane_T_Hanson: I wasn't saying it's bad. As for heat they could use ablative shielding after a weapon like that is single use. It only has to survive once. It's like artillery shells they're not meant to be reused.

@Councilof1: There are physical real world limits on air and speed, and the FRICTION it creates... While it is possible to go Mach 6 + easily, and avoid counter measures, there are many problems - starting with the missiles cannot go super fast in the lower atmosphere - they literally melt and burn up, no matter what the material...... and the space capsules etc., coming in at near orbital velocity, that starts with very high speeds, and in the transition zone between the vacuum of space and the whisp of an atmosphere, and the ablative coatings are just giant brake pads - dumping the heat of friction by gassing, radiating and ablating... Not sure on it any more but say coming in from low earth orbit at 150,000 feet... there is so little gas and the air braking from mach 26 + takes place over such an incredibly long distance, that if the same thing were done in the lower say 30,000 feet, it would just burn up... AND the thing has to go slowly - they talked about ICBM warheads having to slow down on re-entry and all this mega researched and developed technology.... You know why aircraft don't do mach 3 or 4 - like passenger aircraft etc? Because the atmosphere, hasn't changed much in the last few million years... It's the same air the Wright Brothers flew through. - 120 years later, the planes are bigger, faster, carrying loads more passengers and cargo, but they are not going much faster - The very fastest military jets are doing around mach 2.8 at 80,000 feet.. The passenger jets are doing 800Kmh at 35,000 feet - a higher subsonic speed....
