At any altitude, as long as there is enough heat, pressure and oxygen to induce the RAM effect at supersonic velocities.
Look it up on http://en.wikipedia.org/wiki/Scramjet Good place to start
1959
Mach 10+
The SCRAMjet was a type of engine that could "suck" the Hydrogen & Oxygen from the air to make a fuel source. This mean it could last forever.

The rate of change of air pressure as a function of increasing altitude decreases with increasing altitude.

The boiling point depends on altitude (pressure). The effect on the melting point is not significant.
You could use the IF or SUMIF function to do that. There are potentially lots of ways of doing it. How the formula or formulas are constructed is going to depend on the structure of your data.You could use the IF or SUMIF function to do that. There are potentially lots of ways of doing it.

Hypoxia is when your body is deprived of an adequate amount of oxygen. It can cause altitude sickness in people at high altitudes which can be potentially fatal.
